title: How to position submit button on same line as input with Simple Form and Bootstrap?
body: <p>Using Simple Form and Bootstrap, I would like to have the following appear in-line instead of having the submit button below the input select.</p>
  
  <pre><code>&lt;%= simple_form_for :select_rollout, :html =&gt; {:class =&gt; "form-inline"}, do |f| %&gt;
    &lt;%= f.input :rollout_id, collection: @rollout_options, :label =&gt; false %&gt;
    &lt;%= f.button :submit, "Apply" %&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>The following solution only works for inputs (the submit button is rendered outside the div for the inputs):</p>
  
  <pre><code>&lt;%= form.input :city, label: 'City/State/Zip', input_html: {class: 'span3'}, wrapper_html: {class: 'controls controls-row'} do %&gt;
    &lt;%= form.input_field :city, class: 'span1' %&gt;
    &lt;%= form.input_field :state, class: 'span1' %&gt;
  &lt;% end %&gt;
  </code></pre>
