Look at the widget settings! There already is an option to force open the tree. “Force open to: all”
OK, thanks. But if you use 2 widget areas, with two wp-dtree, one with the option “Force open to: all” after the widget is displayed with “Force open to: all” in other areas, the widget will be fully disclosed. Can you fix this?
Or this problem occurs because the option “Cache (recommended!)” is “on”?
