By default, the Tab property is 0. The Tab property specifies the identifier of the item where the grouping items of the current item is shown. Use the Tab property to simulate Tab/Pages into your control. By default, the grouping items are displayed right/bottom after the item. The GroupPopup property specifies the way the grouping items are shown. Using the Tab property you can specify where the current grouping items/submenu is shown. Use the BackColor/HotBackColor properties to specify the background color/visual appearance for the grouping items. Use the BackColor/HotBackColor/SelBackColor/SelHotBackColor properties to specify the background color/visual appearance of a specified item

You can use the Tab property in combination with the following properties:

• Radio/Check to specify a radio or check-type item. Usually this item indicates the page of the tab
• ShowPopupOnChecked property to specify that its current popup to be shown only if checked
• ShowCheckedAsSelected property to show a checked item as selected/highlighted instead displaying the check/radio button

Private Sub Form_Load()

    End With
