<optgroup label="Parent">
<option value="1">Child name</option>
<option value="2">Child name</option>
<option value="3">Child name</option>
</optgroup>
<optgroup label="Parent2">
<option value="1">Child Name</option>
<option value="2">Child name</option>
</optgroup>
<%grouped_options_for_select(@Parent,Child.find(params[:parent_id]),:id,:name)%>

Since this you are using "form_for" you want to use "f.select" not "select_tag" like in my example. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
