A lot of customers that are using the Sliding Menus add-in of AllWebMenus Pro, define their DHTML menus in such a way where the menu system can remember their expanded/collapsed state, when browsing through different pages. For example, when they expand a menu's item, the expanded menu keeps this state after navigating to a different page.

The Sliding Menus add-in of AllWebMenus Pro can easily implement this functionality. You just have to go to the "Style Editor" of your DHTML menu maker and choose the "Sub Groups Style" (or in the "Sub Groups Style+" if you want this functionality to be applied in the menu items that belong to a level greater than two) from the "Available Styles". Afterwards, you have to click on the "Type" property and check the "Remember the menu state..." option as shown in the image below:

If you want this setting not to be applied globally (i.e. you want your menu system to remember the expanded/collapsed state for some of your menu items and not for all), you must use the "Menu Editor" and not the "Style Editor". Then you have to choose each item you want to have this behavior, click on the "All Values" button and define its "Type" property as shown above.
