Hi Joern, A tinsy change in treeview allows for an "active" class to open the tree:
under: switch(settings.persist) { I just added: case "active": var current = this.find(".cur_cat"); if ( current.length ) { current.addClass("selected").parents("ul, li").add( current.next() ).show(); } break; That seems to do the trick. Unfortunately I don't quite know how to pass the category name "cur_cat" into the options. But for me hardcoded is OK right now.
