do this:

the_div = ctx.tag

# when called, this will return option tags
option_generator = the_div.patternGenerator('option')

for k,v in mydict.items():
    # man an option tag
    an_option = option_generator()
    # set the variables
    an_option.fillSlots('value', v).fillSlots('label', k)
    # put it inside the div
    the_div[an_option]

return the_div
