Popover

TIP

This component requires the <client-only></client-only> wrap when used in SSR (eg: Nuxt) and SSG (eg: VitePress).

Basic usage

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

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.

WARNING

v-popover is about to be deprecated, please use virtual-ref as alternative.

Rich content

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

Nested operation

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

Directive

You can still using popover in directive way but this is not recommended anymore since this makes your application complicated, you may refer to the virtual triggering for more information.
