I had a similar issue: I wanted to have a partial in a <code>has_many</code>/<code>belongs_to</code> or <code>has_and_belongs_to_many</code> association which would use checkboxes (checkbox group) instead of the default form widget. I have made an extension (= custom view partial) to <code>rails_admin</code> which allows to easily use checkbox group widget for the related models. It is not exactly your use case (you have a kind of enumeration checkbox group), but you could take inspiration from my template, like all templates in <code>rails_admin</code>, even this mine is in HAML : <pre><code>- selected_ids = (hdv = field.html_default_value).nil? ? selected_ids : hdv - n = 3 - data = [] - all_values.sort {|x, y| x[0] <=> y[0] }.each_with_index do |item, index| - (0..(n-1)).each do |p| - data[p] ||= [] - data[p] << item if index % n == p - data.each_with_index do |slice, c| %div{:class => [:column, "col-#{c}"]} - slice.each do |item| %div.checkbox_field = check_box_tag "#{form.dom_name(field)}", item[1], selected_ids.include?(item[1]), {:id => "#{field.method_name}_#{item[1]}"} %label{:for => "#{field.method_name}_#{item[1]}"} = item[0] </code></pre> Other solution would be to use the default <code>rails_admin</code> enumeration feature (<a href="https://github.com/Juicymo/rails_admin/wiki/Enumeration" rel="nofollow">https://github.com/Juicymo/rails_admin/wiki/Enumeration</a>) and just change it's partial template to use checkboxes instead of adding a custom contant and forms. In case of interest the template and the <code>rails_admin</code> checkbox groups association widget extension is open-sourced on GitHub at: <a href="https://github.com/Juicymo/rails_admin/blob/master/app/views/rails_admin/main/_form_checkboxes_multiselect.html.haml" rel="nofollow">https://github.com/Juicymo/rails_admin/blob/master/app/views/rails_admin/main/_form_checkboxes_multiselect.html.haml</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
