The demonstration Orders database has a main form which does not show any data, and only has buttons which open up the other forms and reports in the database. This is an example of a Menu-Only form. To get a menu-only form, set the Top level block type property in the form to Menu block. The resulting form can have buttons and labels, but does not allow any data controls.
Below is the main form from the demonstration Orders database. In this example, the areas which contain the buttons are nested menu-only blocks, in order to be able to add frames and coloured areas to the form. This effect could be achieved equally well with containers.
