Vue element ui tree hides the selected data and displays it when editing

all kinds of things have been having problems for several days. Please give me a train of thought. I feel like I have a problem with the array and data operation

.

problem description

add a freight template. After the user selects a region, the region cannot be selected or deleted, and the data is echoed when the user edits

the environmental background of the problems and what methods you have tried

put the selected id into an array disabled and store it in vuex, and then delete the edited items from disabled when editing again
but the data on the left side is initialized only once. When editing again, the data will affect each other

what result do you expect? What is the error message actually seen?

selected data is not selectable, selected data can not be selected for time, but there is a problem with echo when editing

Vue.js
Mar.25,2021

solved it by yourself. The key is to reinitialize the data. Every time the box pops up, a copy of the data is copied and passed into the component.
every time you re-render the component, you can use v-if
< synctree VMI if = "reloadTree": data.sync= "tempList" VFI model = "finalData" > < / synctree >
. However, there is a drawback. If there is too much data, the performance is poor. I hope you can find another solution

. 
     handleAdd() {
        this.reloadTree = true
        // 
        this.tempList = deepClone(this.originData)
        // disabled
        this.disabledKeys.forEach(key => {
          this.tempList.forEach(item => {
            if (key === item.id) {
              this.$set(item, 'disabled', true)
            }
          })
        })
        // 
        this.dialogVisible = true
      },

I will sort out a small demo in my spare time. Welcome to my github to watch
