Tabs are the main building block for both forms and dashboards. A tab is a single display page containing data components arranged in group boxes. There can be as many as twenty tabs on a form or a dashboard, but only one tab is seen at a time. The same tab can be used in many different forms or dashboards.
A tab contains one or more group boxes. Group boxes are visual aids used to separate and organize a tab's components into manageable areas. Group boxes contain various types of data components, such as text or numeric fields, tables, graphs and lists.
