Popover

Basic usage

Similar to Tooltip, Popover is also built with BPopper. So for some duplicated attributes, please refer to the documentation of Tooltip.

The trigger attribute is used to define how popover is triggered: hover, click, focus or contextmenu . If you want to manually controll it, you can set :visible.

Virtual Triggering

Like Tooltip, Popover can be triggered by virtual elements, if your use case includes separate the triggering element and the content element, you should definitely use the mechanism, normally we use #reference to place our triggering element, with triggering-element API you can set your triggering element anywhere you like, but notice that the triggering element should be an element that accepts mouse and keyboard event.

Rich Content

Other components/elements can be nested in popover. Following is an example of nested table.

Replace the content attribute with a default slot.

Nested Operation

Of course, you can nest other operations. It's more light-weight than using a dialog.
