Hi all...

  I have to use a select box with multiple selection capability. Also i have to retrieve the selected items from the controller.

I used select_tag. But while retrieving the value i don't get anything in the controller

Please help.

Thanks Suneeta

The two tricks are...

  select_tag 'my_records', ... :multiple => :multiple

The is a trick that helps a form pass an array of results, and your <select> HTML needs the multiple="multiple" attribute.

Post your code if you get stuck!
