Drop -down list in Django

I am writing a simple online store on django 1.9 . The following models are available:

tovar/models.py

    color  (models.model):  color = models.charfield (verbose_name = , max_length =  25 , BLANK =  false , null =  true )  code = models.charfield (Verbose_name = , max_length =  8 , Blank =  true , null =  true )    Tovar  (Models.model):  Color = Models.Manytomanyfield (Color, Blank =  true )

     card/models.py  
    class   car  (models.model):  color = models.charfield (Verbose_name = , max_length =  25 , Blank =  false , null =  true )      in the table in the table  Cart  CART apps is indicated a list of colors of a certain product that should be taken from the  tovar  (ManyTomanyfield fields) table. If you use the Selectmultiple widget, how to implement the output of Manytomanyfield?

You can in the template using a cycle in tags & lt; Select & gt; & lt; Option & GT; Place the desired information from the fields, and then connect for a beautiful multi -sector.

  & LT; Select  class  =  multiple = "" "" "" "" "" "" NAME =  redired =  "" "" "  id  =  "" Yourselectid ""  & gt;  { %  for  m  in  model_context %}  & lt; option value =  & gt; {m.someename}} & lt;/option & gt;  { % endfor %}  & lt;/Select & gt;    in your custom .js file, you can manipulate this thing, Tuing to the  id parameter  tag  & lt; select & gt; . DATA-HIGHLIGHTED = ""> $ (Document). DEADY (FUNCTION () { $ (). Multiselet ({ Columns:  1 ,  Placeholder: ,  search: false,  selectall: true}); });      transmit information from this thing You can click on the button, it must be created in html. 
    $ (Document) .Ready (function () { $ ( ""#SEND-BUTTON "" ). Click (Function () { var fdata = $ (). Serialize ();  $ .Ajax ({ URL: ,   type :  "post" ",  datatype:  "" json "" ,  data: fdata,  Success: function (json) { alrt (); },  error: function (xhr, errmsg, err) { alert ( "" cout not send url to django. error: ""  + xhr.status +  + xhr.responsetext); } }); }); });      yes, with such a cod, you can not create a form at all. All magic takes place in  views.py  and  custom.js .
