I have used atlas default layout which has side bar and top bar. I have placed navigation tree widgets in the side bar container. When i select a sub item from a navigation tree, the sub item will be active(marked as active class). If i select another sub item from different navigation tree, the selected sub item will be active along with the previous selected sub item. But it should disable the the active class from previous selected sub item and make active on only selected sub item. Is there any fix for this? or its mendix default behaviour. Please provide if you have any solutions for it.
