 ### Hierarchical context
 
-By default, a group is **independent** of its position in the groups tree: When selected, only the group's contents are shown. However, especially when using dynamic groups, it is often useful to define a subgroup that **refines its supergroup**, i.e., when selected, entries contained in both groups are displayed. For example, create a supergroup containing entries with the keyword `distribution` and a subgroup containing entries with the keyword `gauss` that refines this supergroup. Selecting the subgroup now displays entries that match both conditions, i.e. are concerned with Gaussian distributions. By adding another refining subgroup for `laplace` to the original supergroup, the grouping can easily be extended. In the groups tree, refining groups have a special icon (this can be turned off in the preferences).

Selecting the subgroup now displays entries that match both conditions, i.e. are concerned with Gaussian distributions. Note that items that only belong to the subgroup `gauss` will not be shown, i.e. for an item to be displayed when selecting `gauss` it is necessary to be assigned to both the subgroup `gauss` and the supergroup `distribution`. By adding another refining subgroup for `laplace` to the original supergroup, the grouping can easily be extended. In the groups tree, refining groups have a special icon (this can be turned off in the preferences).
 
 The logical complement to a refining group is a group that **includes its subgroups**, i.e. when selected, not only the group's own entries, but also its subgroups' entries are shown. In the groups tree, this type of group has a special icon (this can be turned off in the preferences).
