The principles of sub collection wizard lists are exactly the same as on the standard wizard list creation.
Firstly, go to the collection you wish to add the sub collection to and when in the SubCollection section, select create new SubCollection.
After doing so, you will firstly see the properties window appear where you should name and describe the SubCollection that you are creating.
Lists are the 3rd step in this wizard and the creation of them is the same as with standard list design.
Design the list view of your collection by simply dragging the adjacent fields across to the central window.
This will show the data beneath the headings which are made up from the field names.
You can also add in system fields that will provide you with extra detail to your record.
You have the option to add or delete all fields from the list if you wish to do so.
You can also group by a field by dragging and dropping the field above.
The above is demonstrated in the video below.
