How mix jquery based ui packages and ruby on rails

[rubyrookie]

I am trying to use jqx ui that is based on jquqery  I have following questions

1. How do I generate the right id and name for the element without setting the element name and id in the format model name [attribute] ?   Example <%= f.text_field :country_id %> generates

sets the element id and name to bank[country_id]

2.how do i set the form element attributes like action ? Do i just use form_tag to generate the form?

Thanks Anant
