When To Use

TreeSelect is similar to Select, but the values are provided in a tree like structure. Any data whose entries are defined in a hierarchical manner is fit to use this control. Examples of such case may include a corporate hierarchy, a directory structure, and so on.

FAQ

How to get parent node in onChange?

We don't provide this since performance consideration. You can get by this way: https://codesandbox.io/s/get-parent-node-in-onchange-eb1608

Why sometime customize Option cause scroll break?

You can ref Select FAQ.

Why loadData not trigger when searching?

In earlier version, loadData will be triggered when searching. But we got feedback that it will block network when inputting. So we change it to not trigger loadData when searching. But you can still handle async logic by filterTreeNode:

<TreeSelect
  filterTreeNode={(input, treeNode) => {
    const match = YOUR_LOGIC_HERE;

    if (match && !treeNode.isLeaf && !treeNode.children) {
      // Do some loading logic
    }

    return match;
  }}
/>

Why can't popup scroll horizontally?

Just turn off virtual scrolling, because the scrollWidth of the complete list cannot be accurately measured when virtual scrolling is turned on.
