# Select Element iOS Bug - Always Include Disabled Placeholder Option
|
||||
|
||||
**Impact: HIGH** - When a `<select>` element's v-model initial value doesn't match any option, iOS renders it as "unselected" and users CANNOT select the first item. iOS doesn't fire a change event when selecting an already-visually-selected option, leaving users stuck.
|
||||
|
||||
This is a platform-specific bug that only manifests on iOS Safari. Desktop browsers and Android handle this gracefully, making it easy to miss during development. The fix is simple: always include a disabled placeholder option.
|
||||
|
||||
## Task Checklist
|
||||
|
||||
- [ ] Always add a disabled placeholder option with empty value to select elements
|
||||
- [ ] Ensure v-model initial value is empty string to match the placeholder
|
||||
- [ ] Test select inputs on iOS devices or simulators
|
||||
- [ ] Consider this for any user-facing forms, especially on mobile-first apps
|
||||
|
||||
**Problem - iOS users cannot select first option:**
|
||||
```html
|
||||
<script setup>
|
||||
import { ref } from 'vue'
|
||||
|
||||
// Initial value is empty string, doesn't match any option
|
||||
const selected = ref('')
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<!-- PROBLEM: On iOS, "Apple" appears selected but user cannot actually select it -->
|
||||
<!-- Tapping "Apple" does nothing because iOS doesn't fire change event -->
|
||||
<select v-model="selected">
|
||||
<option value="apple">Apple</option>
|
||||
<option value="banana">Banana</option>
|
||||
<option value="orange">Orange</option>
|
||||
</select>
|
||||
|
||||
<!-- selected remains '' even though "Apple" appears highlighted -->
|
||||
</template>
|
||||
```
|
||||
|
||||
**Solution - Add disabled placeholder option:**
|
||||
```html
|
||||
<script setup>
|
||||
import { ref } from 'vue'
|
||||
|
||||
const selected = ref('') // Matches the placeholder option
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<!-- CORRECT: Disabled placeholder ensures user must actively select -->
|
||||
<select v-model="selected">
|
||||
<option disabled value="">Please select a fruit</option>
|
||||
<option value="apple">Apple</option>
|
||||
<option value="banana">Banana</option>
|
||||
<option value="orange">Orange</option>
|
||||
</select>
|
||||
</template>
|
||||
```
|
||||
|
||||
```html
|
||||
<!-- Variant with required attribute for form validation -->
|
||||
<select v-model="selected" required>
|
||||
<option disabled value="">-- Select an option --</option>
|
||||
<option value="a">Option A</option>
|
||||
<option value="b">Option B</option>
|
||||
</select>
|
||||
```
|
||||
|
||||
```html
|
||||
<!-- If you MUST have a pre-selected default, set the initial value to match -->
|
||||
<script setup>
|
||||
import { ref } from 'vue'
|
||||
|
||||
// Set initial value to match an actual option
|
||||
const country = ref('us') // Pre-selects "United States"
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<select v-model="country">
|
||||
<option value="us">United States</option>
|
||||
<option value="uk">United Kingdom</option>
|
||||
<option value="ca">Canada</option>
|
||||
</select>
|

</template>
