are you able to design in what is called a multi-panel layout, such as tab panel or card panel, where one out of many member panels is displayed based on user action or pre-defined event? all I need is the ability to put up overlaying panels, which shows different forms and icons based on whether the user chooses whether he is inside the US or outside. so when he checks a box, one panel is displayed. unchecked, the other panel displays. it is an common thing to do for web developers.
