associating references to controls in cluster

Hello

I am new to Labview OOP coding.

I am trying to hide/unhide a control within a cluster. I realize the controls are available as a 1D array of reference. And I am able to specify an element of the array of references to hide or unhide the specific element. How can I accomplish this (hide/unhide) without knowing or caring about the order of the element in the cluster ? Thanks
