Hi Kamil, Thanks a lot for your suggestion!
I have a few remarks though. The list of cities is dynamic, in the sense that you may add, remove cities from the database at any time using the admin interface. So how can we fetch dynamically the list of available cities to display them in the select widget? Also, isn't there a "recommended" way of doing? Hijacking with javascript seems more like a trick. I may be wrong. Thanks! ;) On Nov 20, 8:13 pm, kamil <[EMAIL PROTECTED]> wrote: > Hi Julien > > The simple way is hijack city select box with javascript. > You add > js=['http://herecomes path to your script'] > to admin options in your model > js can look like this: > > var countries = {'england': ['London','Manchester'], 'france': > ['Paris'] } > > document.forms['your_form'].id_country.onchange = function() > { listCities(this.value) }; > > function listCities ( country ) { > document.forms['your_form'].id_city.options.length = 0 > var l = countries[ country ].length; > for (var i = 0; l > i; i++) { > document.forms['your_form'].id_city.options[i] = new > Option( countries[ country ][i], countries[ country ][i]); > } > > } > > I hope it helps :) > > On Nov 19, 11:54 pm, Julien <[EMAIL PROTECTED]> wrote: > > > Sorry, my "drawing" came out a bit funny in my previous post.
