TreeSelect
Tree selection control.
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.
Examples
import { TreeSelect } from 'antd';
const TreeNode = TreeSelect.TreeNode;
class Demo extends React.Component {
state = {
value: undefined,
}
onChange = (value) => {
console.log(arguments);
this.setState({ value });
}
render() {
return (
<TreeSelect
showSearch
style={{ width: 300 }}

placeholder="Please select"

defaultValue | To set the initial selected treeNode(s). | string|string[] | - |
multiple | Support multiple or not, will be true when enable treeCheckable . | boolean | false |
onSelect | A callback function, can be executed when you select a treeNode. | function(value, node, extra) | - |
onChange | A callback function, can be executed when selected treeNodes or input value change | function(value, label, extra) | - |
allowClear | Whether allow clear | boolean | false |
onSearch | A callback function, can be executed when the search input changes. | function(value: string) | - |
placeholder | Placeholder of the select input | string | - |

disabled | Disabled or not | boolean | false |
showCheckedStrategy | The way show selected item in box. Default: just show child nodes. TreeSelect.SHOW_ALL : show all checked treeNodes (include parent treeNode). TreeSelect.SHOW_PARENT : show checked treeNodes (just show parent treeNode). | enum { TreeSelect.SHOW_ALL, TreeSelect.SHOW_PARENT, TreeSelect.SHOW_CHILD } | TreeSelect.SHOW_CHILD |
treeDefaultExpandAll | Whether to expand all treeNodes by default | boolean | false |
treeDefaultExpandedKeys | Default expanded treeNodes | string[] | - |
treeCheckable | Whether to show checkbox on the treeNodes | boolean | false |
treeCheckStrictly | Whether to check nodes precisely (in the checkable mode), means parent and child nodes are not associated, and it will make labelInValue be true | boolean | false |
filterTreeNode | Whether to filter treeNodes by input value. The value of treeNodeFilterProp is used for filtering by default. | boolean|Function(inputValue: string, treeNode: TreeNode) (should return boolean) | Function |
treeNodeFilterProp | Will be used for filtering if filterTreeNode returns true | string | 'value' |
treeNodeLabelProp | Will render as content of select | string | 'title' |
treeData | Data of the treeNodes, manual construction work is no longer needed if this property has been set(ensure the Uniqueness of each value) | array<{ value, label, children, disabled, disableCheckbox, selectable }> | [] |
treeDataSimpleMode | Enable simple mode of treeData.(treeData should like this: {id:1, pId:0, value:'1', label:"test1",...},..., pId is parent node's id) | false|Array<{ id: string, pId: string, rootPId: null }> | false |
loadData | Load data asynchronously. | function(node) | - |
getPopupContainer | To set the container of the dropdown menu. The default is to create a div element in body , you can reset it to the scrolling area and make a relative reposition. example | Function(triggerNode) | () => document.body |
TreeNode props#
We recommend you to use
treeData
rather thanTreeNode
, to avoid the trouble of manual construction.
