Description
🙋 Feature Request
Right now, the popover position is calculated relative to the trigger element on basis of the triggerRef that we pass to the popover. There are situations where we want the boundary of the popover to be calculated relative to another element.
Taking the below example:
In the above example, we want to open the popover to the left of the sidebar instead of just relative to the trigger element irrespective of where in the sidebar the element is. So I want to set the custom trigger boundary relative to the trigger parent which takes the full width.
💁 Possible Solution
usePopover can accept a new property positionAnchor which can accept a HTML element. This element can be used to position the popover.
🔦 Context
I have many buttons inside the sidebar that act as trigger elements for menu, dropdown etc. We want to open the dropdown outside of the sidebar.
We tried to set the offset by calculating the distance ourselves but we can't use popover's placement logic to place it correctly depending on the space available in other places.
💻 Examples
Figma uses a similar approach to open dropdowns in their sidebar
