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 The trigger attribute is used to define how popover is triggered: hover, click, focus or manual. As for the triggering element, you can write it in two different ways: use the #reference named slot, or use the v-popover directive and set it to Popover's ref.

<template>
  <el-popover
    placement="top-start"
    title="Title"
    :width="200"
    trigger="hover"
    content="this is content, this is content, this is content"
  >
    <template #reference>
      <el-button>Hover to activate</el-button>
    </template>
  </el-popover>

  <el-popover
    placement="bottom"
    title="Title"
    :width="200"
    trigger="click"
    content="this is content, this is content, this is content"
  >
    <template #reference>
      <el-button>Click to activate</el-button>
    </template>
  </el-popover>

  <el-popover
    ref="popover"
    placement="right"
    title="Title"
    :width="200"
    trigger="focus"
    content="this is content, this is content, this is content"
  >
    <template #reference>
      <el-button>Focus to activate</el-button>
    </template>
  </el-popover>

  <el-popover
    placement="bottom"
    title="Title"
    :width="200"
    trigger="manual"
    content="this is content, this is content, this is content"
    v-model:visible="visible"
  >
    <template #reference>
      <el-button @click="visible = !visible">Manual to activate</el-button>
    </template>
  </el-popover>
</template>

<script>
  export default {
    data() {
      return {
        visible: false
      };
    }
  };
</script>
<!--
<setup>

  import { defineComponent, ref } from 'vue';

  export default defineComponent({
    setup() {
      return {
        visible: ref(false),
      };
    },
  });

</setup>
-->

:::

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
  placement="right"
  :width="400"
  trigger="click"
>
  <template #reference>
    <el-button>Click to activate</el-button>
  </template>
  <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>

<script>
  export default {
    data() {
      return {
        gridData: [{
          date: '2016-05-02',
          name: 'Jack',
          address: 'New York City'
        }, {
          date: '2016-05-04',
          name: 'Jack',
          address: 'New York City'
        }, {
          date: '2016-05-01',
          name: 'Jack',
          address: 'New York City'
        }, {
          date: '2016-05-03',
          name: 'Jack',
          address: 'New York City'
        }]
      };
    }
  };
</script>
<!--
<setup>

  import { defineComponent, reactive, toRefs } from 'vue';

  export default defineComponent({
    setup() {
      const state = reactive({
        gridData: [
          {
            date: '2016-05-02',
            name: 'Jack',
            address: 'New York City',
          },
          {
            date: '2016-05-04',
            name: 'Jack',
            address: 'New York City',
          },
          {
            date: '2016-05-01',
            name: 'Jack',
            address: 'New York City',
          },
          {
            date: '2016-05-03',
            name: 'Jack',
            address: 'New York City',
          },
        ],
      });
      return {
        ...toRefs(state),
      };
    },
  });

</setup>

:::

Nested operation

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

:::demo

<el-popover
  placement="top"
  :width="160"
  v-model:visible="visible"
>
  <p>Are you sure to delete this?</p>
  <div style="text-align: right; margin: 0">
    <el-button size="mini" type="text" @click="visible = false">cancel</el-button>
    <el-button type="primary" size="mini" @click="visible = false">confirm</el-button>
  </div>
  <template #reference>
    <el-button @click="visible = true">Delete</el-button>
  </template>
</el-popover>

<script>
  export default {
    data() {
      return {
        visible: false
      };
    }
  };
</script>
<!--
<setup>

  import { defineComponent, ref } from 'vue';

  export default defineComponent({
    setup() {
      return {
        visible: ref(false),
      };
    },
  });

</setup>
