Grouped Fields

You can organize Form items in groups and tabs. To do this, declare Group and Tabbed items in the items[] array. Each group and tab can have their own layout and contain other item types.

To create a group item, assign "group" to the itemType property. To specify a group's title, use the caption property. This demo shows three groups. The Personal Data group is nested in the System Information group.

To create a tabbed item, assign "tabbed" to the itemType property. This demo shows a tabbed item nested in the Contact Information group. The Form uses the TabPanel component to display tabs. You can specify the TabPanel's properties in the tabPanelOptions object. This demo disables the deferRendering property to render TabPanel's content immediately.
