PeopleSoft Fluid has lots of great usability features but the fluid tile navigation has a lot to desire. One of my issues with the navigation is that in the desktop or tablet mode there is no push in or pull out button. This can be really unproductive for busy pages like eCompensation.
Nothing to worry! It is very easy to change the navigation to collapsible. Just add following parameter to the tile url, under structure and content. Now logout and log back in.
&PanelCollapsible=Y
Now you have collapsible menu! You can thank me in the comments ;).
