Replicant - setVisible(false)

System

I have a replicant that I would like to have appear on the form under a specific condition. Can I set the entire replicant to setVisible false, or do I need to loop through and set each field within the replicant to false?

var group = IWDatacapture.getItem("/MetaData/PermissionGroup").getChildren();

I tried to set the group variable to false, but this did not work. Should it?

Thank you!
