### 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
<SelectlistItemHeight={10}listHeight={250}/>
```
Note: `listItemHeight` and `listHeight` are internal props. Please only modify when necessary.
