# Popover
2020-08-13 15:18:26 +08:00
2021-09-17 00:18:50 +08:00
## Basic usage
2020-08-13 15:18:26 +08:00
2022-01-04 09:15:15 +08:00
Similar to Tooltip, Popover is also built with `ElPopper` . So for some duplicated attributes, please refer to the documentation of Tooltip.

:::demo 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
2020-08-13 15:18:26 +08:00
2022-03-24 21:22:46 +08:00
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.

:::demo replace the `content` attribute with a default `slot` .

## Nested operation
2020-08-13 15:18:26 +08:00
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.
