I have setup the theme and for some reason my swatch color appearing as dropdown for configurable product on the product detail page. when i switch the theme to rwd(theme) from sns_aio(theme) it shows as swatch color not as dropdown. Is there anything i am doing wrong in theme setup?

For example for configurable product if i have red, Black and white T-shirt then i have swatch color on category page and a drop down on the product view page. where as I want the swatch colors on product view page instead of dropdown.
