Display warning message when no product option selected? This post is outdated
I have implemented a solution to display "select your size" as the first option in the drop-down list for a product (as per instructions found here: http://wiki.shopify.com/Adding_%27Pick_an_option%27_to_options_drop-downs). Everything is working fine, but I would also like to display a warning message when the "add to cart" button is clicked if no option has been selected (it can appear "broken" to "some people" because nothing happens when you click the button).
Is there anyone out there who could point me to a solution? Even just a hint of a solution?
