Popover
A small panel anchored to what opened it, for content the reader can act on — a form, a set of controls, a detail with a link in it. Reach for Tooltip when the content is only a label, and Drawer when it is a task rather than a detail.
Usage
Examples
With tooltip
A tooltip on the popover's own trigger — the label explains what opens, the popover holds what you do.
Min max width
Width bounds, for content that varies. Let it size to the content rather than pinning it, or short content sits in an empty box.
Min max height
Height bounds with scrolling past the cap. If it scrolls often, the content has outgrown a popover.
