Ideally almost exactly how they have it there. You click make and then the next drop down is a list of all the models I have. The make portion would be the category I would guess, and the model would be the corresponding products in that category. I’ve seen this type of thing on several types of camera repair sites.
I’ve also been messing around with a predictive text function that would make it even easier for the user to pull up there model. After, days of research I’m kind of starting to lean towards the more user friendly predictive text function. This is a breakthrough I’ve had since my post.
Any suggestions would be helpful though.
