You can use something like this :

<select name="display" onChange="submit()" model="versions" view="List">
   <span pattern="listItem">
       <option view="display_value" value="thevalue"><span view="Text"></span>

here is your simple model

def wmfactory_versions(self, request):
	return ["item1", "item2", "item3"]

This will help to autoselect the last selected value :

from twisted.web import  microdom

def wvupdate_display_value(self, request, node, model):
        option = microdom.lmx(node)
        option['value'] = model
        display = request.args.get("display", [""])[0]
        if display == model:
            option['selected'] = "1"

I hope this helps !
