> note: you'd better to use treeData instead of using TreeNode.

| name | description | type | default |
|----------|----------------|----------|--------------|
|disabled | disable treeNode | bool | false |
|key | it's value must be unique across the tree's all TreeNode, you must set it | String | - |
|value | default as treeNodeFilterProp (be unique across the tree's all TreeNode) | String | '' |
|title | tree/subTree's title | String/element | '---' |
|isLeaf | whether it's leaf node | bool | false |

note

1. Optimization tips(when there are large amounts of data, like more than 5000 nodes)
- Do not Expand all nodes.
- Recommend not exist many TreeSelect components in a page at the same time.
- Recommend not use treeCheckable mode, or use treeCheckStrictly.
2. In treeCheckable mode, It has the same effect when click x(node in Selection box) or uncheck in the treeNode(in dropdown panel), but the essence is not the same. So, even if both of them trigger onChange method, but the parameters (the third parameter) are different. （中文：在treeCheckable模式下，已选择节点上的x删除操作、和相应 treeNode 节点上 checkbox 的 uncheck 操作，最终效果相同，但本质不一样。前者跟弹出的 tree 组件可以“毫无关系”（例如 dropdown 没展开过，tree 也就没渲染好），而后者是 tree 组件上的节点 uncheck 事件。所以、即便两者都会触发onChange`方法、但它们的参数（第三个参数）是不同的。）
