Revit - Group Element Parameters Grayed Out

If you have a need to edit elements in a group, you will notice that if you tab and select something, that some element properties can be changed and some cannot.

Notice that Mark is active, but Image is not editable.   Unfortunately we cannot modify the setting that controls how that is editable in a group on built in parameters...which means the only way we can change those values is to Edit the Group.

But for project or shared parameters, we can fix those by changing the Parameter Data Properties.

These settings are what control whether we can tab and select and element in a group to edit, or if we have to Edit the group to fix these, which in that case it will change that parameter value in all instances of that group.

Below is an excerpt from the Autodesk help file

• Values are aligned per group type (default): If an element with this instance parameter is part of multiple groups, the parameter value will be the same for corresponding elements in all group instances. While in Edit Group mode, you can select the element and modify the parameter on the Properties palette. Changing the parameter value for the element in one group will change the value for the corresponding element in all other instances of the same group type.
• Values can vary by group instance: If the element with this instance parameter is part of multiple groups, the parameter value can vary for corresponding elements in group instances. While in Edit Group mode, you can select the element and modify the parameter on the Properties palette. Changing the parameter value for the element in one group will not change the value for the corresponding element in other instances of the same group type.

Below you can see example of some project parameters that have been modified to allow them to vary by group instance.
