Marionette.CollectionView for a select box

expected html

<select> // CollectionView.el
  <option value="modelId">Model.name</option> // ItemView for the model
</select>

<!--
can you have Marionette views that do not have a template without overriding the render method? Overriding the render method is painful as you have to implement  the `isClosed setting plus all the event triggers, so it keeps working with all the Marionette hooks, or am I mistaken?

Same solution, well explained. http://stackoverflow.com/a/18194457/374851

An ItemView can take a collection in to it, and you can access that collection at items inside of the template.

and it's written in document too.
