Rather than attempt to work directly with Form Template and Form Template Parts records, Aptify recommends that you use the Configure Tab feature to modify the tab layout and the Visual Designer to modify the specific fields that appear on a tab. Using the combination of a blank tab (created by the Form Template Tab wizard) and the Visual Designer, you can easily add new data to a form without having to modify a form's existing tabs.
See "Using the Form Template Tab Wizard" on page 303 for for information on how to add a blank tab to a form. See "Modifying Field Layout with the Visual Designer" on page 313 for Using Visual Designer to Modify Field Layout for information on the Visual Designer.
