Close from Content

<template>
  <el-popover placement="top" :width="200">
    <template #reference>
      <el-button>Click</el-button>
    </template>
    <template #default="{ hide }">
      <p>Click button to close</p>
      <el-button @click="hide">Close</el-button>
    </template>
  </el-popover>
</template>

Common Issues

1. Popover Not Closing

Use hide function from slot:

<el-popover>
  <template #default="{ hide }">
    <el-button @click="hide">Close</el-button>
  </template>
</el-popover>

2. Popover Position Issues

Use placement and fallback-placements:

<el-popover
  placement="top"
  :fallback-placements="['bottom', 'left', 'right']"
>
</el-popover>

3. Click Outside Not Closing

Set trigger="click":

<el-popover trigger="click">
</el-popover>

Best Practices

1. Use appropriate trigger: Choose trigger based on use case
2. Set width: Set appropriate width for content
3. Close from content: Use hide function for custom close
4. Virtual triggering: Use for complex trigger scenarios
5. Controlled visibility: Use v-model:visible for programmatic control
