使用movable-area创建一个可移动区域容器
movable-area 是 uniapp 的可移动区域组件。它用于定义可移动视图容器,在其内部可拖拽移动子视图。
在 movable-area 组件中,可以使用 movable-view 组件定义可移动的子视图。movable-view 必须是 movable-area 的直接子节点,不支持嵌套 movable-view。
movable-area 的属性有:
movable-view 的属性有:movable-area 和 movable-view 通常搭配使用,来实现可拖拽排序的列表效果。

以上代码实现了uniapp在小程序端实现菜单拖拽排序，以及显示隐藏指定菜单功能，有点小bug，需要原始代码的可以给我私信留言。当然有更简单的办法 uni-app切片工具也可以实现拖拽排序、菜单排序、导航排序等更多功能！
