cities download form on page brakes modal window!

<fieldset>         <legend>the territory of distribution of ads</legend>          {{ form.country|add_class:"b-input__input js-select" }}         {{ form.districts|add_class:"b-input__input js-select chosen-select" }}         {{ form.regions|add_class:"b-input__input js-select chosen-select" }}         {{ form.cities|add_class:"b-input__input js-select chosen-select" }}         {# form.geo|add_class:"b-input__input" #}      </fieldset>

as explain it, have lot of data (countries, cities), if in php, lock page until retrive datas.

to have shorter loading time, have make in js (ajax).

you load page cities, countries, ... without data.

once page loaded (document.ready), call ajax fill cities, countries , on.
