How to implement multiple select box?

Rails
1

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

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

HTML needs the multiple=“multiple” attribute.

Post your code if you get stuck!
