I want to create a custom property and then group my nodes list by it.
I've created the custom property using the custom property editor and then populated it.
My next step was to Edit All Nodes and change the Grouping Nodes Level 1 field to the custom property I created. However the new custom property does not appear in the drop down list of fields.
Can someone let this newbie know what he's forgotten to do to make the custom property available?
