Did you know...

...that you can group columns/rows in JGoodies FormLayout. Columns/rows in a group will all get the same size. JFormDesigner displays a line connecting the grouped columns/rows.

Select the columns/rows you want to group in the header and select Group from the popup menu.

To remove a column/row from a group, select it and select Ungroup from the popup menu.

You can extend existing groups by selecting at least one column/row of the existing group and the columns/rows that you want to add to that group, then select Group from the popup menu.
