## Popover ### Basic usage Similar to Tooltip, Popover is also built with `Vue-popper`. So for some duplicated attributes, please refer to the documentation of Tooltip. :::demo Add `ref` in your popover, then in your button, use `v-popover` directive to link the button and the popover. The attribute `trigger` is used to define how popover is triggered: `hover`, `click` or `focus`. Alternatively, you can specify reference using a named `slot`. ```html Hover to activate Click to activate Focus to activate ``` ::: ### Nested information Other components can be nested in popover. Following is an example of nested table. :::demo replace the `content` attribute with a default `slot`. ```html Click to activate ``` ::: ### Nested operation Of course, you can nest other operations. It's more light-weight than using a dialog. :::demo ```html
