I want to validate a select field before the item is added to the cart. For example, if a buyer wants to purchase a t-shirt, I want the buyer to select a size before the shirt is added to the cart. The code below validates the select field but the item is added to the cart.

$(function() {
//simple example 1
//click event for first button
$('#btn').click(function() {
$("#form1".valid(); //validate form 1
});

Hello Danny,

Unfortunately there is no a validation option integrated in the shopping cart.
