Simple_form: How to remove .form-control class in check boxes & radio buttons?

[apraditya]

I have the following in my simple form:

<%= f.input :geography_mandate_list,
              as: :check_boxes,
              wrapper_html: {class: mandate_class},
              collection: GeographyMandate.names %>

and it produces:

<span class="checkbox">
  <label for="idea_geography_mandate_list_global" name="idea[geography_mandate_list]">
    <input class="check_boxes optional form-control"
            id="idea_geography_mandate_list_global"
            name="idea[geography_mandate_list][]"
            type="checkbox"
            value="Global">
      Global
  </label>
</span>

I want to remove form-control class from the input tag across the application. How can I do this in the config file? I don't quite get how the config works. I'm using Rails 4.1 and simple_form-3.1.0.rc1. Thank you so much.

PS: You may want to consider taking the class from these input types by default as it's not nice imho.
