A '''tree view''' [widget] presents hierarchical data such that it can be navigated by expanding and contracting nodes of the [tree]. The canonical tree view distributed with [Tk] since 8.5 is '''[ttk::treeview]''' ** Alternative Tk Tree View Widgets ** [tablelist]: a [Multicolumn listbox%|%multi-column] [listbox] and tree widget that has received a good deal of positive review [TkTreeCtrl]: [BWidget::Tree]: [ttk::treeview]: bundled with [Tk] since 8.5.
