FAQ

Why sometime search will show 2 same option when in tags mode?

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

When I click elements in dropdownRender, the select dropdown will not be closed?

You can control it by open prop: codesandbox.

I don't want dropdown close when click inside dropdownRender?

Select will close when it lose focus. You can prevent event to handle this:

<Select
  dropdownRender={() => (
    <div
      onMouseDown={(e) => {
        e.preventDefault();
        e.stopPropagation();
      }}
    >
      Some Content
    </div>
  )}
/>

Why sometime customize Option cause scroll break?

Virtual scroll internal set item height as 24px. 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.

Default virtual scrolling will create a mock element to simulate an accessible binding. If a screen reader needs to fully access the entire list, you can set virtual={false} to disable virtual scrolling and the accessibility option will be bound to the actual element.
