In this update, a new UI component is also added, which is the view component movable-view, which needs to be used together with movable-area. Simply put, it is a container that supports dragging content within a specified area.

Let’s look at a simple example:

<movable-area style="height: 200px;width: 200px;background: red;">
 <movable-view direction="all" style="height: 50px; width: 50px; background: blue;">
 </movable-view>
</movable-area>

Interface

We used movable-area to set a draggable area (red) of 200x200 size, and then placed a draggable area of ​​​​50x50 in this area Content movable-view (blue), the direction of this draggable content is set to all, which means it can be dragged in any direction.

Drag Demonstration

<movable-area style="height: 200px;width: 200px;background: red;">

<movable-area style="height: 200px;width: 200px;background: red;">
 <movable-view direction="none" x="50" y="50" style="height: 50px; width: 50px; background: blue;">
