Subgroups in Time Tracker
Users in Time Tracker can be organized into a hierarchical tree of top group and subgroups. Without subgroups you only have one group of users, which is an organization top group. You can create subgroups in it, and also in each subgroup no matter how deep. Use
Subgroups: Configure option on the
Group page to manage subgroups. This option is available to logged-in users with the
"manage_subgroups" access right.

Here is how Subgroups view looks like. The
Group dropdown on top of the page allows to select a parent group, for which a subgroup list is displayed below, together with an
Add button to add new ones.

Navigating between Subgroups
Use the
Group dropdown to navigate between subgroups in an organization. Red circles in the dropdown represent subgroup level in an organizational tree. For example, two circles indicate 2 steps up to the top group.
When group changes, the page header with user details changes also to reflect that you are currently operating
on behalf of a different group, similar to the on behalf mechanism for users in the same group.

Other pages in such mode now display views for the on behalf group.
Projects lists their projects,
Users lists their users, and
Reports run for users in this group. To revert back to home group use the
Group dropdown again and change the group.
Subgroup Settings
Each subgroup has its own settings: its own roles, its own plugins, language, users, projects, tasks, and everything else.
- To change subgroup settings use the Group tab in Time Tracker.
- To change subgroup plugins use the Plugins tab.
- To change subgroup name use the Advanced settings: Configure link on the Group tab.
When creating a subgroup, all parent group settings are copied over to new subgroup but can be changed if necessary.
