javascript show additional select list upon choice selection
Hi, Please could you tell me what JavaScript I would need to add in order to achieve the following scenario:
1) client selects an option from a form select list (for example that chose "categories").
2) as soon as they make the selection, a secondary form select list appears under it.
The idea comes from wanting to create a coupon system where the client can chose the coupon type (either delivery, category or all products). So obviously I wouldn't need to display the form select list for categories if the client chooses either "delivery" or "all products".
