Placement and Offset

You can place dropdown any direction you want. Offset is calculated relative to placement prop. We use main and cross offset. Means main will be relative to placement direction while cross is perpendicular. auto placement will be bottom by default, but will change to top if it is not possible to display on bottom.

Place on cursor
#

You can render dropdown content on cursor position. It is useful to use cursor props with auto-placement so if content do not fit target it will be placed somewhere else.

Prevent overflow
#

By default dropdown content is rendered as body child. This way we prevent any overflow. In example below overflow: hidden of green box is ignored. But we still able to respec overflow by changing target prop. In example below overflow: hidden of red box is hiding dropdown content.
