I was asked at work to look at a page design made by one of the designers. It displays a list of company products, and the user is asked to select only one of the products then press a continue button.
To select an option however, the designer used a checkbox for each product, which in my eyes is wrong from a usability perspective as checkboxes are for multiple selections; whereas radio is for exclusive choice. The designer however said his boss told him to use checkboxes because, and I quote, "they look better". When told a radio button should be used, he said it should be made to look like a checkbox.
He's very stubborn when it comes to things like this, so I was hoping anyone could help me out in providing a grounded explanation why using a checkbox in this case is wrong on all counts.
If you think I'm wrong, then please say so ... with a grounded explanation why
Thanks in advance.
