Since the cosmetic of controls in an array must be identical for all of them, you can't selectively hide cluster elements using property node. That will affect all elements. The solution would be to show only one element at a time.
The only thing different from element to element is data content. Using a boolean control, you can change its appearance and its size depending of its value. The trick is to make a boolean that is small and transparent when false and large and opaque when true. When true (large), the boolean can overlap and hide other parts of the area.Unfortunately
LabVIEW is buggy when dealing with such booleans with different sizes. Try to put the attached boolean on a FP and the relative offsets of different true
/false piceture are messed up.
