Required field indicators in Arabic forms

An Arabic form can show a required asterisk beside the wrong label, announce no required state to assistive technology, or reject a field that the interface called optional. Moving the asterisk to the other side fixes only one of those problems.

Treat the indicator as a promise: this information is needed to complete the current task. The visible label, accessible state and validation rule must describe the same requirement. If any of them changes, update the others.

This guide uses a community radio programme proposal. A programme title is required. Additional information about a recorded segment becomes required only when the proposer includes that segment. Those rules should be understandable before submission, in Arabic, without relying on a red symbol or an English legend.

Choose a convention people can understand before submitting#

Use visible Arabic wording such as مطلوب when a short status can fit beside the label. An asterisk is also possible, but explain its meaning before the first field that uses it. W3C's H90 technique describes required indicators associated through labels or group legends, including the explanation needed for symbols.

For the programme proposal, choose one convention and apply it consistently. Do not put a star beside one required field, colour another label red and leave a third unmarked because its requirement lives only in the backend schema.

An alternative is to explain that all fields are required unless marked optional, then label the exceptions. That can work when it accurately describes the form. Check that later conditional sections and reusable components preserve the convention rather than assuming the opening instruction applies to a different set of fields.

Do not make red the only signal. A coloured label can communicate emphasis while failing to distinguish required from optional without that colour. W3C's Use of Color guidance explains why meaning needs another visible distinction, such as text or an explained symbol.

Show the requirement before the proposer starts entering information. A required message that appears only after a failed submit describes a mistake too late to serve as the initial instruction.

Give a native control native required semantics#

For the programme title, use a real label and the native required attribute:

<div lang="ar" dir="rtl">  <label for="programme-title">    عنوان البرنامج <span aria-hidden="true">(مطلوب)</span>  </label>  <input id="programme-title" name="programmeTitle" type="text"         dir="rtl" required aria-describedby="programme-title-help">  <p id="programme-title-help">اكتب العنوان المقترح للبرنامج.</p></div>

The label identifies the field. The visible Arabic word explains the status. Native required exposes the requirement and participates in constraint validation for this supported input type. MDN's required reference documents that behavior.

In this pattern, the visual status span is hidden from assistive technology because the native required state supplies that information separately. The accessible label still contains the field's actual name. Verify the resulting announcement with your browser and screen-reader combinations rather than assuming one exact spoken phrase.

Hiding the span is not a general instruction to hide required information. It works here because the control has a corresponding native state. A custom widget without equivalent semantics cannot become accessible by hiding its only explanation.

Keep the label's for value matched to the actual input ID. A component can show the right marker while associating its label with a wrapper or a nonexistent control. MDN's label reference explains the explicit relationship and label activation.

Native required validation still needs a translated failure experience. An Arabic label does not guarantee that a browser-generated error will be Arabic. Test the empty-submit state separately from the initial label and marker.

Check what counts as an answer for each control#

Native required validation is not a judgement that an answer is useful. For a text input, a string containing spaces is not the empty string. If the programme title must contain something beyond whitespace, define that additional rule and explain its correction in Arabic. Do not assume the required marker or native missing-value check supplies it. MDN's valueMissing reference distinguishes a missing required value from other validity failures.

A default value can also satisfy the native requirement without representing a new answer. Do not place example text into the title's actual value and expect required to force the proposer to replace it. Keep examples in help or a suitable placeholder, separate from submitted content.

For a required select, inspect the value of its initial instruction option. A visible instruction such as “choose a category” must not accidentally submit a real category identifier before the person chooses. Check the control's exact configuration against the select documentation, rather than treating its displayed caption as its stored value.

The same product distinction applies to radio defaults. A preselected format may satisfy a required group, but it does not prove the proposer actively reviewed that choice. Decide whether the workflow accepts that default. A star cannot turn an already selected value into a requirement for an additional deliberate action.

Place the marker relative to the label, not the screen#

An asterisk has no inherent Arabic reading direction. Its apparent position depends on its surrounding text and layout. There is no useful rule that every required star on an Arabic page must occupy one physical side regardless of the label.

Specify the intended reading order. In this guide's design, the reader encounters the Arabic field name first, followed by its required marker. In a horizontal RTL label row, that places the name toward the right and the trailing marker toward the left.

For a short label, a layout that expresses that order is clearer than absolute positioning:

<p lang="ar" dir="rtl">الحقول المعلّمة بنجمة (*) مطلوبة.</p><div lang="ar" dir="rtl">  <label class="programme-label" for="starred-title">    <span>عنوان البرنامج</span>    <span class="programme-label__marker" aria-hidden="true">*</span>  </label>  <input id="starred-title" name="programmeTitle" type="text" required></div>

.programme-label {  display: inline-flex;  align-items: baseline;  gap: 0.4rem;  max-inline-size: 100%;} .programme-label > span:first-child {  min-inline-size: 0;} .programme-label__marker {  flex: none;}

This is an alternative presentation of the title field, not a second title input to add to the same form. The form-level explanation is translated and the star is decorative to assistive technology because the input retains native required semantics.

The source order follows the intended sequence; the RTL row supplies the corresponding horizontal layout. Adding row-reverse on top of that direction reverses the sequence again. MDN's flex-direction reference describes this interaction.

The supplied layout measurements used Chromium 151 on September 24, 2026; Firefox and Safari were not measured. Check the complete label and marker in your supported browsers, including wrapping and text enlargement, rather than treating a single short-label screenshot as proof.

Keep the marker beside its own field at narrow widths#

An absolutely positioned star can be separated from the label that explains it. A long Arabic label may wrap while the star remains fixed to a field corner or appears closer to the next control.

Keep the marker in the label's layout. The short-label example allocates a separate flex item for it while allowing the text item to shrink. That is not a promise that every label will fit. Test the actual Arabic strings at the narrowest supported width and with increased text size.

If a required word or symbol becomes detached from its field, change the label layout rather than shrinking the marker until it is difficult to notice. A persistent status line or a label that wraps as ordinary text may be a better choice for a long instruction. Preserve the association even when the visual arrangement changes.

Do not move an Arabic label to the left merely because its input contains an LTR value. For a demo-recording URL, the editing value can be LTR while the Arabic label and required convention remain in the RTL interface. The marker belongs to the label's status, not to the URL string.

Avoid placing markers in placeholders. The indication disappears when the user types, and an empty placeholder-only field lacks a persistent visible label. A proposer reviewing a filled form should still be able to identify which fields are required.

Distinguish required state from an accessible name#

A required marker and the control's name answer different questions. The name identifies the field. Required state describes whether an answer is needed. Help and errors provide further instructions.

Do not replace an Arabic visible label with aria-label="Required", or with a translated equivalent containing only the status. The user would lose the field's identity. Adding an English required suffix to every accessible name can also leave the visible form translated while its interaction remains partly English.

For a native input, prefer native semantics rather than redundantly adding aria-required="true" everywhere. For a supported custom widget role, aria-required can expose required state, but it does not implement validation, focus management or submission behavior. Its presence is not a substitute for those responsibilities.

Check which rendered element receives the semantics. A library's outer field wrapper may show the marker while its internal input lacks required. Conversely, the real input may be required while the visible component still says optional. Inspect the interactive element, not just the design-system component's props.

Also distinguish boolean HTML attributes from ARIA string values. This does not make a native field optional:

<!-- Problem: a present boolean attribute remains enabled. --><input type="text" name="programmeTitle" required="false">

Remove required or set the DOM property's boolean value to false when the native requirement no longer applies. MDN explains the presence-based behavior of HTML boolean attributes. Do not serialize application booleans into attribute strings without checking what the rendered HTML means.

Describe requirements for groups at the group level#

The programme proposal asks for one production format. That is one required choice, not a demand to select every radio option.

<fieldset lang="ar" dir="rtl">  <legend>صيغة البرنامج (مطلوب)</legend>  <label>    <input type="radio" name="productionFormat" value="live" required>    مباشر  </label>  <label>    <input type="radio" name="productionFormat" value="recorded" required>    مسجل  </label></fieldset>

The shared name defines the native radio group. A required group needs a selected option, and applying required consistently across these radios does not make both choices necessary. MDN's radio input reference explains group validation. The fieldset element supplies the grouping and legend relationship.

Checkboxes behave differently. Putting required on each checkbox in a group requires each of those boxes to be checked; it does not mean “choose any one.” If the product needs at least one topic selected from several checkboxes, implement that group rule and explain it in Arabic. MDN's checkbox reference documents the individual required behavior.

Do not put a star beside every option when the requirement belongs to the question. Repeated markers can obscure whether the user must choose one option, several options or complete each item. Write the group's actual instruction, then verify both keyboard interaction and the announced group context.

Update conditional requirements as one state change#

Suppose a proposer may include a recorded segment. Its title is required only when that branch is active. Keep branch visibility, native validation and the visible indication synchronized.

This fragment illustrates that JavaScript-controlled branch; a non-JavaScript workflow needs its own usable path for collecting the segment details:

<div lang="ar" dir="rtl">  <label>    <input id="include-segment" type="checkbox" name="includeSegment">    يتضمن البرنامج فقرة مسجلة  </label>  <div id="segment-details" hidden>    <label for="segment-title">      عنوان الفقرة المسجلة <span aria-hidden="true">(مطلوب)</span>    </label>    <input id="segment-title" name="segmentTitle" type="text" disabled>  </div></div>

const includeSegment = document.querySelector("#include-segment");const segmentDetails = document.querySelector("#segment-details");const segmentTitle = document.querySelector("#segment-title"); function syncSegmentRequirement() {  const active = includeSegment.checked;  segmentDetails.hidden = !active;  segmentTitle.disabled = !active;  segmentTitle.required = active;} includeSegment.addEventListener("change", syncSegmentRequirement);syncSegmentRequirement();

When active, the branch shows its required wording and enables a required input. When inactive, the field is disabled and not required. Hiding a wrapper alone does not establish the control's validation or submission policy. MDN describes hidden separately from disabled; disabled controls do not participate in constraint validation or normal form submission.

This implementation preserves the typed segment title while the branch is inactive, but omits the disabled field from native submission. Decide whether preserving it for a possible return matches your product. Do not erase someone's entry just to remove a required marker.

Any application-owned error summary must follow the same branch change. A hidden section should not retain a correction link directing the proposer to an unavailable field. Re-run the synchronization after restoring a draft or changing this checkbox through application code, and validate the same conditional rule on the server.

Keep optional wording and validation consistent#

If the product marks optional fields instead of required ones, render that wording from the same requirement state as validation. Do not maintain a separately translated “optional” label that survives after the field becomes mandatory.

Test the inverse transition as well: a field that becomes optional should lose its obsolete required state and any missing-value error caused by the previous rule. A remaining syntax error may still apply if the user has entered a value. Optional means an answer may be omitted, not that every nonempty answer is valid.

Read-only and disabled states need their own interpretation. A read-only title already supplied by the system may be required by the record schema, but the user cannot complete a missing value there. Native required validation does not have its normal effect on a read-only input. Explain any task needed to resolve the missing information rather than presenting an impossible required edit.

For an unavailable field, distinguish the current editing task from an administrative requirement that applies elsewhere. Do not show an unexplained star on a disabled control and expect the proposer to know whether submission is blocked, the value will be supplied later or the field is irrelevant to their branch.

These decisions belong in the form's data contract. If a reused component can only accept a decorative showAsterisk flag, add a requirement state that also reaches its real control and validation path. The marker should be derived from the rule, not become a second rule to remember.

Some requirements cannot be known until earlier answers or saved proposal data have loaded. Treat that as an unresolved state, not an optional field. Showing “optional” briefly and then rejecting the same field can make a proposer distrust the instruction even if the final marker eventually becomes correct.

Resolve the relevant branch before presenting an actionable completion instruction, or explain what choice determines the requirement. When a restored proposal includes the recorded segment, initialize its visible details and native required state from that saved choice. Do not wait for the proposer to toggle the checkbox merely to synchronize the form.

Reset is another transition to verify. If the checkbox returns to its original state, refresh the branch and requirement state after the reset completes as part of the application's reset lifecycle. Resetting field values alone does not establish that separately managed visibility, errors and indicators have returned to the same state.

Do not confuse required with already invalid#

A required field may be empty while the person is still completing the proposal. The indicator describes what is needed; an error describes a failed or evaluated answer. Showing the marker does not mean the field should immediately announce an error.

Choose a validation timing policy and apply it consistently. On a failed submit, identify the missing field in Arabic and explain the correction. After correction, remove stale error text and invalid state while keeping the required indication, because the requirement itself has not disappeared.

Keep help, required state and errors available together without unnecessary repetition. A screen reader may receive the field name, native required state and associated descriptions. Listen to that sequence in the combinations you support rather than adding hidden “required” text to every layer just in case.

Use the same field name in errors and labels. If the visible title label uses one Arabic term and the error uses another, the user has to infer which field is missing. A programme proposal with several titles makes that ambiguity more noticeable.

Finally, test the submission path the product actually uses. A custom request handler can bypass native interactive validation. The visible marker and required attribute must still agree with application and server rules, even when the browser is not responsible for presenting the failure.

Review the instruction where the marker is encountered#

An opening explanation can be missed if a long form reveals another section later or places a required group inside a dialog. Put the meaning of an asterisk where it will be encountered before its first relevant use, without turning every label into a repeated paragraph.

Translate that explanation along with labels, optional wording and validation. A star is visually unchanged between languages; its English legend is not. Include this text in localization review instead of treating it as a design-system constant outside the Arabic catalog.

Give translators the convention, not just isolated strings. They need to know whether a word is a separate status badge, part of the label's sentence or an opening instruction governing the whole form. Keep punctuation and wording consistent across those uses. If the interface language changes while a proposal is open, update optional wording, marker explanations and existing validation messages together, while preserving the underlying requirement and the entered values.

If CSS generates the marker, inspect what remains when styles fail or the component renders in another surface. Native semantics may still expose the requirement, but sighted users also need the visible convention. A real text or symbol node can be easier to translate, inspect and associate than a marker assembled from unrelated pseudo-elements.

Check long Arabic labels, wrapped group legends and the actual font. The indicator should not cover a letter, resemble part of the label's punctuation or drift toward a neighbouring field. For a layout failure, inspect the label's direction and containing box separately from the input's value direction.

Test the visible promise against the actual rule#

Create a requirement inventory for the programme form, including each conditional branch. For each field or group, record what the user sees, which element exposes required semantics and which validation rule enforces it. Any disagreement is a defect even if the marker occupies the intended side.

Inspect the rendered native attribute or ARIA state rather than only the component configuration. Test both directions of a conditional change, including a branch that already contains text and one that has an error. Check the payload so disabled fields and the server's branch rules do not contradict one another.

An accessibility-tree check cannot prove that a small star is visible or close enough to its label. A screenshot cannot prove native semantics or validation. Review both, using real Arabic labels and keyboard interaction rather than an English layout with translated screenshots.

A free Ritla scan can report R071: Untranslated form labels / validation / help text. Required semantics and conditional rules need direct verification too; Arabic localization testing helps include the marker explanation and failed-submit states in that review.
