Hi
I’m trying to create a dynamic mattress/bed and have two questions about how to do this.

1, select the size of the mattress from a drop down menu and have both the X & Y dimensions change.

2, when a single is selected have one pillow in the middle and on a double have 2 at ¼ and ¾ along the bed.

If anyone knows where I can find a good tutorial on creating dynamic components it would be appreciated.

Thank you for your help.
