layui treeselect

Layui doesn't have a built-in component called "treeselect". However, you can achieve a similar functionality by using the Treeview component provided by Layui. Here's an example of how you can implement a tree-like select using Layui's Treeview:

1. Include the necessary CSS and JavaScript files for Layui in your HTML file:

<link rel="stylesheet" href="https://cdn.staticfile.org/layui/2.5.6/css/layui.css">
<script src="https://cdn.staticfile.org/layui/2.5.6/layui.js"></script>

2. Create a container element for the tree-like select:

<div id="treeselect"></div>

3. Initialize the Treeview component and define the data for the tree nodes:

layui.use(['layer', 'jquery', 'tree'], function () {
  var layer = layui.layer,
    $ = layui.jquery,
    tree = layui.tree;
  
  var data = [{
    title: 'Node 1',
    id: 1,
    children: [{
      title: 'Node 1-1',
      id: 2
    }, {
      title: 'Node 1-2',
      id: 3
    }]
  }, {
    title: 'Node 2',
    id: 4
  }];

  // Render the tree view
  tree.render({
    elem: '#treeselect',
    data: data,
    click: function (obj) {
      console.log(obj.data); // Selected node data
    }
  });
});

In this example, the `data` variable contains an array of objects representing the tree nodes. Each object has a `title` property for the node's display text and an `id` property for identification purposes. You can customize the data structure according to your needs.

The `click` event handler is triggered when a node is clicked. You can access the selected node's data through the `obj.data` property and perform any necessary actions.

Note that you may need to adjust the CSS and JavaScript file paths according to your project's setup.
