values
A special property that represents the selected values in a <select> element, usually a <select multiple>. The special property is needed because the DOM's native value property on a multiple select only gives you one of the selected options' values.

Binding to values in your can-stache template is useful to get a list of the selected values:
<select multiple values:bind="colors">
<option value="red">Red</option>
<option value="green">Green</option>
<option value="blue">Blue</option>
</select>
This will two-way bind to a "colors" property in the ViewModel.
