• Here is my simple example code:

  
  var tg = Ti.UI.createTabGroup({
  });
  
  tg.addTab(Ti.UI.createTab({
      window: Ti.UI.createWindow({
          title: 'almafa',
          backgroundColor: 'red'
      }),
      title: 'alma'
  }));
  
  tg.addTab(Ti.UI.createTab({
      window: Ti.UI.createWindow({
          title: 'kortefa',
          backgroundColor: 'blue'
      }),
      title: 'korte'
  }));
  
  var win = Ti.UI.createWindow();
  
  var nav = Ti.UI.iPhone.createNavigationGroup({
     window: win
  });
  
  var splitwin = Ti.UI.iPad.createSplitWindow({
      detailView: nav,
      masterView: tg
  });
  
  splitwin.addEventListener('visible',function(e)
  {
      if (e.view == 'detail')
      {
          e.button.title = "Master";
          win.leftNavButton = e.button;
      }
      else if (e.view == 'master')
      {
          tg.open();
          win.leftNavButton = null;
      }
  });
  
  splitwin.open();
  

• Yes! It is posible to do almost anything you want. What exactly are you trying to do? Add a Tabgroup to the detail view, or a Tabgroup to all the view and on top of it have the detail? both ways are posible. Just create a Main Window and add both your Tabgroup and SplitView.
