Setting Group Properties

You can assign properties to a group, including the group’s name, activation action, timespan, and location. Most of the properties apply only when the group is locked and determine the group’s look and behavior. You can also set a Project Tree group as a radio group. All items in the group are then mutually exclusive, i.e., only one item can be selected at any time.

To set the group’s properties:

1. Right-click the parent group, and then from the shortcut menu, select Properties. The Multi-Edit property sheet is displayed.

2. Click the Group tab and set the following parameters:
