Description

Hope to add methods to expand and collapse tree table dynamically

[MikuBlog]

Now, I can only use V-IF to force the refresh of subcomponents to dynamically expand and collapse the tree list.

How to use V-IF for that?

Define a reactive property, such as isExpanded.

Then force the table to render

this.isExpanded = false
this.$nextTick(() => this.isExpanded = true)
