I am designing a frame shop that sells custom sized frames. I need the visitors to be able to select a width and height of 5 - 80" plus be able to add fractions as well. Here is a screenshopt of what I am trying to achieve:



As you can see there is another attribute after the width and height selection that offers fractions. After the width of 12 visitors will need to be able to select another attribute of 1/8, 1/4, 3/4, etc to give the exact size. I figure I can align this via css with another add-on. I really need the fractions. Is adding another attribute for the width and height possible?

As it is now adding a width and height attributes from 5 - 80 is going to be time consumming. If I have to do this with only one attribute to include the fractions it's going to be really time consumming and cluttered. It just makes more sense and is neater if I can add another attribute for the fraction instead of including it into the first box.
