Use this dialog to give your group a name. Simply enter the desired name and acknowledge by pressing "OK". The name of the group does not have to be unique. There may be groups with the same names in your pages.
The widget "Identifier" is only interesting for advanced users. You can give your group a unique identifier (UID) here, which no other group on this page may have. This unique identifier can be used to access the group directly from custom code. The identifier you specify here will be used by the Hollywood script when it creates the group so you can use it to refer to the group from your custom code. See Code dialog for details.
