title: Simple_form bootstrap style inline-form not working properly
body: <p>I have a working twitter bootstrap install and simple form generates the following:</p>
  
  <pre><code>&lt;form accept-charset="UTF-8" action="/find_map" class="simple_form form-inline" id="new_location" method="post" novalidate="novalidate"&gt;&lt;div style="margin:0;padding:0;display:inline"&gt;&lt;input name="utf8" type="hidden" value="&amp;#x2713;" /&gt;&lt;input name="authenticity_token" type="hidden" value="p5CSoidWaoGMfHY0/3ElWi0XJVg6Cqi9GqWRNlJLBQg=" /&gt;&lt;/div&gt;
          &lt;div class="control-group string required"&gt;&lt;div class="controls"&gt;&lt;input class="string required" id="location_address" name="location[address]" placeholder="Address" size="50" type="text" /&gt;&lt;/div&gt;&lt;/div&gt;&lt;input class="btn" name="commit" type="submit" value="Find!" /&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Somehow the "Find!" button won't appear on the same line as the search box. Any ideas?</p>
  
  <p>Thanks!</p>
  
  <p>UPDATE:</p>
  
  <p>Sorry I should have mentioned that all the markup is generated by simple_form based on the following:</p>
  
  <pre><code>&lt;%= simple_form_for @location, :url =&gt; find_map_path, :html =&gt; { :class =&gt; 'form-inline' } do |f| %&gt;
  
          &lt;%= f.input :address, :label =&gt; false, :placeholder =&gt; "Address" %&gt;
          &lt;%= f.submit "Find!", :class =&gt; 'btn' %&gt;
  
  &lt;% end %&gt;
  </code></pre>
  
  <p>So, really, there seems to be an issue with the generated markup, even though I have run the bootstrap install for simple_form, etc. </p>

  <p>The above image shows a straight html form</p>
  
  <pre><code>&lt;form class="form-inline"&gt;
    &lt;input type="text" class="input-small" placeholder="Email"&gt;
    &lt;button type="submit" class="btn"&gt;Sign in&lt;/button&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>...above the one generated by simple_form.</p>
