Why is this not creating a multi-select box in a Rails form?

Question

The code is straight forward.

<%= f.select(:categories, options_for_select(@categories), {:multiple => true, :size => 10}) %><br />

This is creating a single select box. Not one where multiple ones can be selected. Rails 3.1.3.

:multiple is a html_option

<%= f.select(:categories, options_for_select(@categories), {}, {:multiple => true, :size => 10}) %><br />
