Usage

Basic Usage

Use v-model to control the name of active panels

<van-collapse v-model="activeNames">
  <van-collapse-item title="Title1" name="1">Content</van-collapse-item>
  <van-collapse-item title="Title2" name="2">Content</van-collapse-item>
  <van-collapse-item title="Title3" name="3" disabled
    >Content</van-collapse-item
  >
</van-collapse>

export default {
  data() {
    return {
      activeNames: ['1'],
    };
  },
};

Accordion

In accordion mode, only one panel can be expanded at the same time.

<van-collapse v-model="activeName" accordion>
  <van-collapse-item title="Title1" name="1">Content</van-collapse-item>
  <van-collapse-item title="Title2" name="2">Content</van-collapse-item>
  <van-collapse-item title="Title3" name="3">Content</van-collapse-item>
</van-collapse>

export default {
  data() {
    return {
      activeName: '1',
    };
  },
};

Custom title

<van-collapse v-model="activeNames">
  <van-collapse-item name="1">
    <template #title>
      <div>Title1 <van-icon name="question-o" /></div>
    </template>
    Content
  </van-collapse-item>
  <van-collapse-item title="Title2" name="2" icon="shop-o">
    Content
  </van-collapse-item>
