Some DataGroup properties in a Catalog Item are grayed out and cannot be modified.
The "Editable" flag is not checked on for the property in the DataGroup Catalog Editor, for example:
Note that the editable attribute is generally unchecked for a valid reason so take care when enabling editing for certain properties.
1. Open the DataGoup Catalog Editor.
2. Select the Catalog Item on the left side and on the right side look in the "Editable" column.
4. If a check mark is not in the box, when appropriate check it to make the property editable.
