I'm writing a new module in DNN 6 (Same question for DNN 5). By default you have some default tabs for settings in module settings section of any module you put in a particular page. For example in the picture below, we've got "module settings", "permissions" and "page settings".
The question is that how can I add more tabs (more than one) in settings section of the module. For examlple one tab for "general settings" and another one for "advanced settings".
you can add any code you need in ascx and add codes in code behinde in update and load methods. this code can help you: http://www.dotnetnuke.com/Community/Community-Exchange/view/question/id/240.aspx
