Some time ago, the project needed to use two-way list selection. I wanted to use select directly. It turned out that some styles were not supported, so I had to use div to simulate the following. The function was basically implemented and available. You need to add other functions by yourself, such as displaying multiple items in the list. Column data, etc.
