A label (defined as a custom control) that helps to group related fields in an applet. The FormSection label expands to fit the region where you place it. To set it apart, the label appears against the FormSection color defined in the cascading style sheet.
NOTE: In non-grid layout form applets, the control may not expand to fit within the layout editor, but it does render correctly at run time.
Figure 58 shows an example FormSection control rendered in the user interface.
