I am creating a template and need to use 4 different specific colors/gradients I created wit the 4-color gradient effect. I would like for it to work like a radio button, so if you turn one on, the others are off.
So far, I have attached the opacity of each gradient to a checkbox which toggles them on and off. But how do I go about joining all 4 checkboxes in a slider control or angle control? So that the client can just slide it and get only 4 options.
