javascript - jquery uses the append() method to add, for example, easyui's combotree to make a tree-shaped drop-down box. Please help.

Question

Hello everyone, I am new to jquery and easyui. At present, I want to implement a function. Click "Add Button" and a selectable tree drop-down box will pop up for selection and submission.
The current implementation method is to declare an element and then append it to the form. But the pop-up drop-down box cannot pop up the tree map.

The current phenomenon is that the select written directly in the html works well, but the select added through the add button cannot be clicked (the same for org and org2). The styles of the two are even different, as shown below:

Please give me some advice on how to make the drop-down box generated by add work. Thank you very much~

I know what’s going on...You have to create the element first and then declare the combotree attribute, otherwise it won’t load...
