Something with The Collider?!

Questions & Answers

I put two objects in my project;and I need hide one of them by clicking;the two all have the property of Collider;The object A is in the Object B.
when I click Object B ,the Object B is hidden.this is ok;
But ,after the object B is hidden,there is nothing happening when I click the Object A;
I find I can’t click the object A,why?
how can I finish it?
how can I make the collider property of one object invalid?
