First select the Configuration Pack the Picklist Set will be associated with and click on the Manage Picklist Sets Icon from the ribbon.

The main Picklist Sets dialog will be displayed.

The options are: Create Picklistset, Edit Picklistset Name, Manage Picklistset, Delete an Picklistset (as long as it is not in use within a project), and Close the dialog.

Press Create and choose an appropriate name and description for the set. Press Save to commit the changes.

The newly created set will now appear in the main dialog.

To add picklists to the newly created set click the Manage Picklists button. From here you will be presented with a dialog that allows you to select a Picklist group from the drop-down list. This list is the exhaustive list from the configuration pack and will show all picklist groups available.

Select a group for example Sample Information-Type. You will see a list of all available picklists in that group on the left. To allocate a picklist from that group to the set simply select a picklist and press the arrow cursor.

Important Note

If you don't allocate any picklist to the right "Allocated picklist" box, by default the system will assume that the entire picklist is utilised. This is to avoid users needing to reallocate picklists for each group each time they create a new picklist set. 

After selecting those that you wish to add from that group into the set, you must press Save to commit the changes.

If you select a different group from the drop down before pressing save you will receive a warning message.

Once you have saved the picklists from that group added to the set you can select another group from the drop-down.

Repeat the process of adding picklists from their groups into the set. When finished you can close the dialog.
