   @on-select-change="chentreelick"
   :data="treedata"
    expand-node
 ></Tree>
</Scroll>

5. Add the following code to return:

treedata: [
    {
     title: "parent 1",
     chenshow: false,
     expand: true,
     children: [
      {
       title: "parent 1-1",
       chenshow: false,
       expand: true,
       children: [
        {
         title: "leaf 1-1-1",
         chenshow: true,
        },
        {
         title: "leaf 1-1-2",
         chenshow: true,
         selected: true,
