Product Options
Most products have options, whether it be size, color, add-ons, etc. The NebuCart system can support up to 20 option lists per product, but it is unlikely that you will use that many for a single product.

Simple Option List
To make an option list as space efficient as possible, NebuCart supports only select, or drop down menus for options. To create a simple list of size options for our example shirt (product ID "NC_Shirt"), the code would look lik this:

<select name="NC_Shirt_opt">
<option value="Small">Small</option>
<option value="Med">Medium</option>
<option value="Lrg">Large</option>
<option value="XLrg">Xtra Large</option>
</select>


Before the customer adds the shirt to their cart, they have the option of picking a size. By default, the first item in a select list is selected should the customer not pick an option. You can change which item is selected by default by adding the text "selected" in the option tag of choice.

Let's say the customer picked a medium shirt and added it to their cart. When the cart displays, the option "Med" would be displayed in the options column for that item.

Now if the customer returns to that catalog page and selects a different option, say a Small shirt, and adds it to their cart, the cart will display both a small and medium shirt in the cart.

More Options
Now, let's assume that you're not only selling different sized shirts, but different colors as well. To add an option list for this, the code would be:

<select name="NC_Shirt_opt1">
<option value="White">White</option>
<option value="Tan">Tan</option>
<option value="Green">Red</option>
<option value="Black">Black</option>
</select>


Easy right? You'll notice that we named this added option list "NC_Shirt_opt1". This is to give it a unique name so that NebuCart can use it. For each additional option list for a given product, you'll need to increment the Field Suffix by 1. Otherwise, errors will occur.

So if the customer selected a Small, Tan shirt and added it to their cart, the options column would reflect those option choices.

Multiple Select Options
You may have a case where you can give the customer the option of picking more thanone option from a single list. This is easily done by adding the multiple property to the select menu. This is a property of HTML drop downs that allow a user to select more than one item from a list. When you create a multiple drop down, it's a good idea to add a display size (size="N") to the select as well so that they can see more than one choice at a time. Here's how a multiple select definition would look:

<select name="NC_Shirt_opt" size="3" multiple>

Cost Additive Options
Some times, options can cost you, the merchant, extra. So why not pass on the value? Let's take a look at our size option for the product NC_Shirt. It may be that you want to charge the customer an extra $2.95 for picking the extra large shirt. In that case, all you need to do is add that cost to the value property of that option like so:

<option value="XLrg|2.95" >Xtra Large (Add $2.95)</option>

Now when the customer picks the extra large shirt, the cost of the shirt (originally $19.95) would be $22.90! It's that easy. One note: The customer should always be aware of any additional costs to the product, so make sure that you put the added cost either in the text of the option or that it's readily viewable somewhere on the catalog page!
