They work.
The first:
<%= select_tag("bags[]", options_for_select(@bags.collect { |bb|
[bb.bag_type, bb.id] },
@ruser.bags.collect { |ub| ub.id }), {:multiple => true, :id
=> "bags"}) %>
the second:
<%= select_tag "bags[]", options_for_select(@bags.collect { |bb|
[bb.bag_type, bb.id] }, :multiple => true, :id => "bags") %>
Obviously you must have a ruser and bag model, that code is in the
form used to create a new ruser.
