Component Type:UniStickyHeaderElement
吸顶布局容器
注意:暂时仅支持作为list-view、sticky-section的子节点, sticky-header不支持css样式!当一个容器视图设置多个sticky-header时,后一个sticky-header会停靠在前一个sticky-header的末尾处。

父元素滚动过程中,某个元素有固定到父元素顶部的需求
需求其实就是元素吸顶。可将需要吸顶元素放入sticky-header组件中,sticky-header组件作为父元素的子元素,放到吸顶元素原来的位置即可。
示例:
<list-view id="list-view" style="flex: 1; background-color: #f5f5f5;">
<sticky-header>
<!-- 固定到父元素顶部的元素 -->
<text style="padding: 20px; background-color: #f5f5f5;">向上滑动页面,体验sticky-header吸顶效果。</text>
</sticky-header>
<list-item v-for="index in 20" :key="index" style="padding: 15px; margin: 5px 0;background-color: #fff;border-radius: 5px;">
<text class="text">itme-content-{{index}}</text>
</list-item>
</list-view>
注意

父元素滚动过程中,多个元素有固定到父元素顶部的需求。
父元素中多个元素吸顶需要使用sticky-section组件。sticky-section组件作为sticky-header组件的父容器。sticky-section组件会控制子元素的滚动吸顶业务。sticky-section组件之间可通过push-pinned-header属性控制吸顶重叠时是否上推。
示例:
<list-view id="list-view" style="flex: 1; background-color: #f5f5f5;">
<sticky-section v-for="sectionId in 3" :id="sectionId" push-pinned-header=false>
<sticky-header>
<text style="padding: 20px; background-color: #f5f5f5;">sticky-header吸顶--{{sectionId}}</text>
</sticky-header>
<list-item v-for="index in 20" :key="index" style="padding: 15px; margin: 5px 0;background-color: #fff;border-radius: 5px;">
<text class="text">itme-content-{{index}}</text>
</list-item>
</sticky-section>
</list-view>
