Rails 3 + Simple Form: Specifiy label class when using f.association

Question

How can I specify the label class when using f.association instead of f.input in simple_form?

For example, this works:

f.input :name, :label_html => { :class => 'some-class' }

But this doesn't

f.association :periods, :as => :check_boxes, :label_html => { :class => 'some-class' }

Meaning that the label related to :name will have some-class as part of its class, but the label related to :periods won't. Any way to do this without changing f.association to f.input? Thank!

that's strange. It works on new app, I've just tested it. Could you show your simple_form.rb initializer? — Vasiliy Ermolovich

not sure what you are expecting to see but label_html adds that custom class only to attribute's input not to every checkboxes. — Vasiliy Ermolovich

You're right, nash, it adds that class to the attribute's input and not to every checkbox. I would like to add the class to all the checkboxes — sauronnikko

I think you can't add custom class to each label but you can do it for each item wrapper, e.g:

<%= simple_form_for(@user) do |f| %>
  <%= f.association :group, as: :check_boxes, item_wrapper_class: 'custom-class' %>
  <%= f.button :submit %>
<% end %>

This no longer works in the latest version and adds a custom class to another wrapper span :/ - any solution to changing the label class? :(

Hackeron Try with input_html: { class: 'yourclass'}
