A SubCollection is a subset of a Collection. SubCollections are particularly helpful when there are many instances of a similar activity. For example, you might create a Collection called “Vacations” and then create SubCollections called “At the Beach”, “Trip to Japan”, etc. to divide the category up further.

To create a SubCollection, create a new Collection and then drag it on top of an existing Collection name. The SubCollection will inherit the color of the parent Collection.

You can change the color of a separate SubCollection by clicking once on the name to select it and then choosing a color from the Color Palette button located on the top right part of the Edit window. SubCollections can also have their own titles, keywords and descriptions.
