KoolTreeView - Great PHP TreeViewKoolTreeView - Great PHP TreeViewFullVersion released on 25/11/2016

Features - State persistence

The treeview's state will persist when you refresh the page:
  • My Properties
    • Hardware
    • Software
    • Books

Description & Sample code

KoolTreeView supports state persistence, which the open/close state of TreeNodes will not change if you revisit the page. To enable this functionality, you need to set keepState property to "onpage" or "crosspage".

If you use "crosspage" state persistence, the tree in group of pages must have the same id.

You may decide how long the state will be kept from the last visit by setting keepStateHours to the number of hours you want.
