The following is a bit more graphic designer friendly:

<select name="city" nevow:data="citiesList" nevow:render="sequence">
	<option nevow:pattern="item" nevow:render="city" value="1">

def data_citiesList(self, context, data):
     return {"New York":'1', "Los Angeles":'2'}.items()

def render_city(self, context, data):
     return context.tag(value=data[1])[data[0]]

The only problem with the above is if you put something inside the 
option for the template, say:

<option nevow:pattern="item" nevow:render="city" value="1">

You will see ned prepended in each option rendered by nevow.  Does 
anyone know how to overwrite the template contents of the option?
