I've created a form in which to specify a category for a product on the product entry page. I can't seem to add the category that the customer selects to the order model. I've checked the orders in the control panel and they do not seem to be storing the category. Does anybody know how to add a selected category to the order model?
<form id="values" method="POST">
<input type="hidden" name="action" value="commerce/cart/updateCart">
<input type="hidden" name="redirect" value="cart">
...
<select id="chocOptions" name="chocolateOptions" class="options">
<option title="selectOption">Select Option</option>
{% for category in craft.categories.group('chocolate') %}
<option value="{{ category.title }}">{{ category.title }}</option>
{% endfor %}
</select>
...
</form>
