Starting from Portal 12.0.12, we introduced a new Portal Admin setting: Portal.KeepSidebarExpanded
This setting allows you to configure the sidebar to be expanded by default for all users.
However, please note that this is a global configuration, not a per-user preference.
Currently, the portal does not persist the user’s toggle state (expanded/collapsed) across browser sessions.
We are aware of this limitation. In an upcoming Portal 12 version, we plan to redesign the sidebar behavior and introduce more flexible interaction modes, such as:
Hover mode (default)
Stick mode (always expanded)
Click mode
Potentially allowing users to fully hide the sidebar
This redesign will give user more option to customize Portal for there desire.
