问题 I'm trying to build a TreeView from scratch in Vue. This is my code so far. The first problem I'm encountering is that the content of the subfolders (like child folder 1 ) is not being displayed. The second problem is that minimizing the subfolders minimizes the whole treeview. Could anyone help me understand why these two errors in functionality are occurring and how to fix them? 回答1: your code only dealed with the first level of your folders, you should recursively revoke your tree

Here's what I've been trying: main.js

Furthermore I have written the following code to evaluate the colors for the html -section: switch (this.item.itemType) { case 'car': this.color1 = '#39ac39'; this.color2
