Tab control-multiple cards or hidden groups?

I have a separate group of controls for each tab, and by group I really mean "group". This way I just have the selectionChanged handler in the tab object show and hide the corresponding group. In fact I name each group "grp<tabname>" so if for example I am showing the sites group:

on selectionChanged pTab
   put "grp" & pTab  into tGroup
   show group tGroup
   -- loop to hide other groups
end selectionChanged

Depending on who is logging in, some of the input fields and buttons are different, and there may be multiple steps to the login and registration process. The main complication is that some buttons and fields need to be in different places in each group. Rather than write code to reposition them, I use controls with the same name, but in different locations in groups. The name of a field is important, as it corresponds to a field name on a remote database. This means I have to do some extra coding to make sure I get the field (which may have the same name as another field in another group) that is in the group that's showing when I get or set its contents. Ultimately, I'm hoping this makes the interaction between text fields and my MySQL db pretty seamless.

An app I am working on currently uses a tab control with five tabs that currently go to different cards. The cards concerned all share a number of other controls responsible for about 60% of their area with the tabbed panel taking the rest. Some of the panels are simply variations of another (e.g. Simple vs complex search).
