Popover

Placement

Popover has 9 placements.

Use attribute content to set the display content when hover. The attribute placement determines the position of the Popover. Its value is [orientation]-[alignment] with four orientations top, left, right, bottom and three alignments start, end, null, and the default alignment is null. Take placement="left-end" for example, Popover will display on the left of the element which you are hovering and the bottom of the Popover aligns with the bottom of the element.

Basic usage

Popover is built with ElTooltip. 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 control 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 virtual-ref 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.

replace the content attribute with a default slot.

  <div style="display: flex; align-items: center">
    <el-popover placement="right" :width="400" trigger="click">
      <template #reference>

      </template>
      <el-table :data="gridData">
        <el-table-column width="150" property="date" label="date" />
        <el-table-column width="100" property="name" label="name" />
        <el-table-column width="300" property="address" label="address" />
      </el-table>
    </el-popover>

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.
