最近做项目需要这样的需求，当用户点击标签栏按钮，向下弹出菜单，再次点击，收回菜单。接下来通过本文给大家介绍微信小程序实现弹出菜单功能，感兴趣的朋友一起看看吧

需求

点击标签栏按钮，向下弹出菜单，再次点击，收回菜单

要解决的问题

  1. 标签栏三栏样式，标签栏固定不动；

  2. 点击标签栏弹出菜单，并且出现透明遮罩；

  3. 遮罩优先级在弹出框之下；

  4. 弹出框内标签的设置；

  5. 滚动栏滚动条的隐藏

如何解决？

  1. 弹性布局，横向，三者平分整栏;

  2. 状态监听点击事件，数据控制hide或者show,通过rgba设置透明度

  3. 弹出框设置z-index；

  4. 弹性布局flex 横向排列 超出后wrap 然后space-around控制间距

::-webkit-scrollbar {
width: 0;
height: 0;
color: transparent;
}
