<el-collapse v-model="activeNames" @change="handleChange">
  <el-collapse-item title="Consistency" name="1">
    <div>
      Consistent with real life: in line with the process and logic of real
      life, and comply with languages and habits that the users are used to;
    </div>
    <div>
      Consistent within interface: all elements should be consistent, such as:
      design style, icons and texts, position of elements, etc.
    </div>
  </el-collapse-item>
  <el-collapse-item title="Feedback" name="2">
    <div>
      Operation feedback: enable the users to clearly perceive their operations
      by style updates and interactive effects;
    </div>
    <div>
      Visual feedback: reflect current state by updating or rearranging elements
      of the page.
    </div>
  </el-collapse-item>
  <el-collapse-item title="Efficiency" name="3">
    <div>
      Simplify the process: keep operating process simple and intuitive;
    </div>
    <div>
      Definite and clear: enunciate your intentions clearly so that the users
      can quickly understand and make decisions;
    </div>
    <div>

      users to identify and frees them from memorizing and recalling.
    </div>
  </el-collapse-item>
  <el-collapse-item title="Controllability" name="4">
    <div>
      Decision making: giving advices about operations is acceptable, but do not
      make decisions for the users;
    </div>
    <div>
      Controlled consequences: users should be granted the freedom to operate,
      including canceling, aborting or terminating current operation.
    </div>
  </el-collapse-item>
</el-collapse>
<script>
  export default {
    data() {
      return {
        activeNames: ['1'],

      handleChange(val) {
        console.log(val)
      },
    },
  }
</script>
<!--

    <template #title>
      Consistency<i class="header-icon el-icon-information"></i>

      life, and comply with languages and habits that the users are used to;

      design style, icons and texts, position of elements, etc.
