The main navigation bar has the elements
- brand element (static)
- sites (static)
- tabs (dynamic, closable)
- permanent tools (static)
- personal tools (configurable, static)
- personal menu (static)
If there is not enough space the elements move to the off-canvas menu. The implementation leads to empty toolbars if users have to many sites quicky. This can quickly become a problem for authors, a new mechanism must be implemented.
The new solution should move the sites and tabs to a new "more" menu, item by item. The menu appears when needed, If there is enough space, the menu hides again.
See jira for an example.
