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.

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:
<TreeSelectfilterTreeNode={(input, treeNode) => {const match = YOUR_LOGIC_HERE;if (match && !treeNode.isLeaf && !treeNode.children) {// Do some loading logic}return match;}}/>
Just turn off virtual scrolling, because the scrollWidth of the complete list cannot be accurately measured when virtual scrolling is turned on.
