Dropdown

Toggleable menu for displaying lists of links and actions.

Basic usage

Hover on the dropdown menu to unfold it for more actions.

:::demo The triggering element is rendered by the default slot, and the dropdown part is rendered by the slot named dropdown. By default, dropdown list shows when you hover on the triggering element without having to click it.

<el-dropdown>
  <span class="el-dropdown-link">
    Dropdown List<i class="el-icon-arrow-down el-icon--right"></i>
  </span>
  <template #dropdown>
    <el-dropdown-menu>
      <el-dropdown-item>Action 1</el-dropdown-item>
      <el-dropdown-item>Action 2</el-dropdown-item>
      <el-dropdown-item>Action 3</el-dropdown-item>
      <el-dropdown-item disabled>Action 4</el-dropdown-item>
      <el-dropdown-item divided>Action 5</el-dropdown-item>
    </el-dropdown-menu> 
  </template>
</el-dropdown>

<style>
  .el-dropdown-link {
    cursor: pointer;
    color: #409EFF;
  }

Triggering element

Use the button to trigger the dropdown list.
