## FAQ

### Why sometime search will show 2 same option when in `tag` mode?

It's caused by option with different `label` and `value`. You can use `optionFilterProp="label"` to change filter logic instead.

### The dropdown is closed when click `dropdownRender` area?

See the instruction in [dropdownRender example](#components-select-demo-custom-dropdown-menu).

### Why sometime customize Option cause scroll break?

Virtual scroll internal set item height as `32px`. You need to adjust `listItemHeight` when your option height is less and `listHeight` config list container height:

```tsx
<Select listItemHeight={10} listHeight={250} />
```

Note: `listItemHeight` and `listHeight` are internal props. Please only modify when necessary.

### Why a11y test report missing `aria-` props?

Select only create a11y auxiliary node when operating on. Please open Select and retry. For `aria-label` & `aria-labelledby` miss warning, please add related prop to Select with your own requirement.
