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.

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:

<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.
