트리 그리드(TreeGrid)

FlexGrid를 사용하여 JavaScript에서 강력한 TreeGrid를 구축하십시오. 데이터 항목에 하위 항목 모음이 포함된 경우 FlexGrid의 childItemsPath를 사용하여 데이터를 TreeGrid로 표시할 수 있습니다. 예를 들어, 'children' 속성이 있는 'person' 개체 목록을 생각해 보십시오. 'children' 속성에는 더 많은 person 객체의 배열이 포함되어 있습니다. 이를 동종 계층 구조라고도 합니다. 아래의 TreeGrid는 표식을 최상위 사람 목록에 바인딩하고 childItemsPath 속성을 'children'으로 설정하여 빌드되었습니다.
