FAQ
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.
