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.

<el-popover
  ref="popover1"
  placement="top-start"
  title="Title"
  width="200"
  trigger="hover"
  content="this is content, this is content, this is content">
</el-popover>

<el-popover
  ref="popover2"
  placement="bottom"
  title="Title"
  width="200"
  trigger="click"
  content="this is content, this is content, this is content">
</el-popover>

<el-button v-popover:popover1>Hover to activate</el-button>
<el-button v-popover:popover2>Click to activate</el-button>
<el-popover
  placement="right"
  title="Title"
  width="200"
  trigger="focus"
  content="this is content, this is content, this is content">
  <el-button slot="reference">Focus to activate</el-button>
</el-popover>

:::

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.

<el-popover
  ref="popover4"
  placement="right"
  width="400"
  trigger="click">
  <el-table :data="gridData">
    <el-table-column width="150" property="date" label="date"></el-table-column>
    <el-table-column width="100" property="name" label="name"></el-table-column>
    <el-table-column width="300" property="address" label="address"></el-table-column>
  </el-table>
</el-popover>

<el-button v-popover:popover4>Click to activate</el-button>

:::

Nested operation

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

:::demo

<el-popover
  ref="popover5"
  placement="top"
  width="160"
  v-model="visible2">
  <p>Are you sure to delete this?</p>
  <div style="text-align: right; margin: 0">
    <el-button size="mini" type="text" @click.native="visible2 = false">cancel</el-button>
    <el-button type="primary" size="mini" @click.native="visible2 = false">confirm</el-button>
  </div>
</el-popover>

<el-button v-popover:popover5>Delete</el-button>
