How to deal with white space in Alloy

Take the following code snippet:

<View id='container'> <View id='child' width=100 height=100/> <View id='child1' width=100 height=100/> <View id='child2' width=100 height=100 /> <View id='child3'width=100 height=100 visible='false' bottom='0'/> </View> I have a container and nested in it, child views.

Say I make child 3 visible false, the problem is the window will not resize accordingly and there will be white space for where child 3 is. As it is rendered, but hidden.

How can I deal with white space in titanium.

Thanks
