This policy setting allows you to configure adjoining form regions to be always expanded.

If you enable this policy setting, you may enter the adjoining form region name as the Value name and the Value data as "1" (without quotes).  This ensures that users see the whole adjoining form region and cannot collapse it.  This works for both Explorer and Inspector.

If you disable or do not configure this policy setting, adjoining form regions are not expanded.
