Sidebar toggle button configuration.

  Hi,   1- How to choose the region that should be collapsed/expanded by clicking the toggle button? If there is an implicit criteria that connects the toggle button and the target region, what is that criteria?   2- Also the toggle button documentation states that there are General properties->Region, Mode, Initially open options, but I can't find those options (I'm using modeler version 7.5.1).   Thanks

These settings can be configured on a scroll container region. Select a region and look at the property grid. 

I guess the documentation was not updated when these properties were moved...
