Advanced Show/Hide can be used to select all components in order to show them or hide them.
I use the PartNo Custom Property and set up a selection criteria like
OR PartNo IsNot 0
and then I can check the box to show or hide selected items. Since the selection criteria will always be true (unless you have a PartNo of 0 (zero) the selected items will either all show or all hide.
You can save favorite criteria so that you don't have to recreate them every time.
Advance Show/Hide is found in the Configuration Feature Tree by RMB on a configuration.
