one dropdown to another

Hi all! 

I am not a complete idiot when it comes to excel but far from the wizardry like you guys here. 

So here goes; 

I'm creating a template for ordering panels (cabinetry). 

Panels have a color and a structure (the relief/type of skin). 

What I would like to accomplish is when we select a manufacturer from a dropdown I automatically get another dropdown with the corresponding structures that manufacturer has. 

Any wizards?...
