Groupings are a way of organising groups. For example, you may have a grouping that contains all project groups, another grouping for tutorial groups, etc. In many cases, groups must be within groupings before you can use them for activities.
In the topic, locate the Administration block
Click Users, then Groups
Click on the Groupings tab
Click Create grouping
Give the grouping a name
Next to the grouping, click the Show groups in groupings icon
Select the relevant groups from the list on the right, and click Add to include them in the grouping. (Note you can select multiple groups by holding down the CTRL button)
