View Full Version : Local Persistence in Switch Menu Acting Flakey

1) Script Title: Switch Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex1/switchmenu.htm

3) Describe problem: Have been using the Switch Menu script for three years now with excellent results. In my past applications I had the persistence feature activated sitewide. I currently have a new application in which I would like to have the persistence active locally. When I test it though the persistence only takes affect after I have selected a submenu item for the second time. For example, the first time I select a submenu item it directs me to the linked page but the menu collapses. I reopen the menu and select the same submenu item and the tree correctly stays open. My applicable code is below. Unfortunately, I cannot post a URL of the example since the application is within a electronic catalog which is installed into a kitchen and bath design program called 20-20 Design. Any assistance would be greatly appreciated.
