If so, what are the parameters recorded in your log file when posting the form? And what is your code in the controller that receives the form data? If you can select multiple items, then there should be multiple items in the parameters, so if this is still not working for you I suspect it is because of the way you read the values... -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I can select multiple items using mouse while pushing ctrl key,but can not select multiple items only using mouse.After selecting mutiple items and submitting, there is only one item submitted in the params. Collection:@ng_category_groups is the return value of some method which i called in the view in the help file.I have not designed the method to recieve form data because the recieved params include only one item.

To return multiple items, the name must end in "[]", so: <%=select_tag("products[]",option_groups_from_collection_for_select (@ng_category_groups,"options","name","product_id","product_name"),:multiple=>true)-%> If this is in a form for a specific object (say "my_object") and you want the products returned to be grouped in the params hash for this object, then use the name "my_object[products][]". -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
