Menu that provides navigation for your website.

Top bar

Top bar NavMenu can be used in a variety of scenarios.

::: demo By default Menu is vertical, but you can change it to horizontal by setting the mode prop to 'horizontal'. In addition, you can use the submenu component to create a second level menu.

<el-menu theme="dark" :default-active="activeIndex" class="el-menu-demo" mode="horizontal" @select="handleSelect">
  <el-menu-item index="1">Processing Center</el-menu-item>
  <el-submenu index="2">
    <template slot="title">Workspace</template>
    <el-menu-item index="2-1">item one</el-menu-item>
    <el-menu-item index="2-2">item two</el-menu-item>
    <el-menu-item index="2-3">item three</el-menu-item>
  </el-submenu>
  <el-menu-item index="3"><a href="https://www.ele.me" target="_blank">Orders</a></el-menu-item>
</el-menu>
<div class="line"></div>
<el-menu :default-active="activeIndex2" class="el-menu-demo" mode="horizontal" @select="handleSelect">
  <el-menu-item index="1">Processing Center</el-menu-item>
  <el-submenu index="2">
    <template slot="title">Workspace</template>
    <el-menu-item index="2-1">item one</el-menu-item>
    <el-menu-item index="2-2">item two</el-menu-item>
    <el-menu-item index="2-3">item three</el-menu-item>
  </el-submenu>
  <el-menu-item index="3"><a href="https://www.ele.me" target="_blank">Orders</a></el-menu-item>
</el-menu>

<script>
  export default {
    data() {
      return {
        activeIndex: '1',
        activeIndex2: '1'
      };
    },
    methods: {
      handleSelect(key, keyPath) {
        console.log(key, keyPath);
      }
    }
  }
</script>
