ctTree is an enhanced hierarchical tree / outline control ideal for displaying document headings, index entries, file directory structures, and any other information that can be organized in a hierarchical format.
The ctTree component consists of a series of node objects. Each node may have its own text (or label), bitmaps, check boxes and radio buttons. Each node item in the list may also have subordinate items or children. These children are represented as indented levels. When a parent item is expanded, its immediate child items become visible. When the parent item is collapsed, child items are hidden.
