Select an accessory drop-down menu

[DML73]

Is there a mod available to add an accessory/option drop-down menu to display under the price box on product info pages, so the customer needs to select an option (for example color or size) before the Add to Cart button is clickable?

That is already in Zen Cart
I you go in your admin to Catalog=>Attributes Controller and select the product.

Next to the options you will see a row of coloured dots. The last one (red) makes the option requid.
Enable it.

Now when you try to put the product in your shopping cart you will get a warning telling you, you will need to make a choice
