                                        the string '??' in the URL will be replaced by the value
                                        corresponding to to the selection

Example:

==

To do an incremental search on the ‘name’ field of the ‘product’ table:

<< In your template: >>

<%= text_field_with_select_auto_complete :product, :name, {}, { :row_count => 4, :min_chars => 2, :redirect_url => {:action => ‘show’, :id => ’??’}} %>

<< In your controller: >>

select_auto_complete_for :product, :name

Do not forget to include the file dtcontrols.js in the head of your pages as well as prototype.js and controls.js
