-### 可切换值的多选框
-
-多选框单独时，除了可以表示为是否选中的逻辑值以外，你还可以设定其选中和未选中所表示的值。
-
-:::demo 使用`true-label`和`false-label`可以自定义选中时和未选中时的值，可以为`String`或`Number`类型。
-
-```html
-<template>
-  <el-checkbox
-    v-model="isValid"
-    true-label="可用"
-    false-label="不可用">
-    {{isValid}}
-  </el-checkbox>
-</template>
-<script>
-  export default {
-    data() {
-      return {
-        isValid: '可用'
-      };
-    }
-  };
