select_tag ignores :multiple option

Reported by John Woods | January 24th, 2011 @ 09:52 PM

Normally, select_tag should allow a :multiple option, which produces:

<select id="..." multiple>...</select>

In 3.1 beta, the :multiple option is ignored. This is true not only for select_tag, but for all of the helper methods that make use of select. I have tested collection_select and FormHelper select.

<%= form_for :neighborhood do |f|
  f.label :species_ids, 'species'
  f.select :species_ids, [['Human', 'Hs'], ['Mouse', 'Mm'], ['Yeast', 'Sc']], :multiple => true
<% end %>

This produces a drop-down list when it should produce a multi-select box.

I think you're missing a {} in the f.select.. select and select_tag are both working properly on rails@master

<%= form_for :neighborhood do |f| %>
  <%= f.select :species_ids, [['Human', 'Hs'], ['Mouse', 'Mm'], ['Yeast', 'Sc']], {}, :multiple => true %>
  <%= select_tag :species, options_for_select([['Human', 'Hs'], ['Mouse', 'Mm'], ['Yeast', 'Sc']]), :multiple => true %>
<% end %>

John, did that solve your problem? I believe it should. Do comment back here if it did so that I can close the ticket.
