SELECT within SELECT

Rails
1

I am trying to create a drop down of categories and that same drop down
should also have subcategories of currently selected category.

for category drop down I use something like

<%= collection_select(:category, :id, Category.find(:all), :id, :name)
%>

but I would like to do something like

<%= collection_select(:category, :id, Category.find(:all).each do |cat|
if cat.name?(currently_selected) Subcategory.find(:cat.name), :id,
:name) %>

any ideas?.

I think the closest you can come to this with real HTML would be
using option_groups_from_collection_for_select; subcategories
will be selectable but not categories.

And that’s just the way ‘optgroup’ works, nothing to do with Rails.

HTH!
