title: Cannot align form-group line inside form-inline inside a panel
body: <p>The following code describes a panel in one of my webpages:</p>
  
  <pre><code>  &lt;div class="row" id="tool_row"&gt;
  &lt;div class="panel panel-info" id="edit_toolbar" style="width:66%"&gt;
  
    &lt;div class="panel-heading"&gt;
      &lt;h1 class="panel-title"&gt;&lt;b&gt;Herramientas&lt;/b&gt;&lt;/h1&gt;
    &lt;/div&gt;
  
    &lt;div class="panel-body"&gt;      
      &lt;div class="form-inline" style="width:100%"&gt;          
        &lt;button class="btn btn-primary" onclick="loadActForEdition(-1)"&gt;Nueva actividad&lt;/button&gt;  
  
        &lt;p style="margin-top:10px"&gt;&lt;label class="control-label"&gt; Opciones de Filtrado &lt;/label&gt;&lt;/p&gt;
  
        &lt;label class="control-label"&gt; Últimos &lt;/label&gt; &lt;input class="form-control" id="ndays" style="width:5%" onkeypress='getEnter(event,"fillTaskTable")'&gt; &lt;label class="control-label" style="margin-right:10px"&gt; días &lt;/label&gt;
  
        &lt;select data-placeholder="Filtrar por proyecto" class="chosen" id="proyect_box" onchange=fillTaskTable()&gt;&lt;/select&gt;
        &lt;select data-placeholder="Filtrar por estado" class="chosen" id="status_box" onchange=fillTaskTable()&gt; &lt;/select&gt;                
  
        &lt;div class="form-group pull-right"&gt;
      &lt;label class="control-label"&gt; Número de resultados &lt;/label&gt; &lt;input class="form-control" id="nrows" style="width:15%" value=30 onkeypress='getEnter(event,"fillTaskTable")'&gt;
        &lt;/div&gt;
  
      &lt;/div&gt; &lt;!--form_inline--&gt;               
    &lt;/div&gt; &lt;!--Panel body--&gt;
  
  &lt;/div&gt;  &lt;!--del panel--&gt;
  </code></pre>
  
  <p>However it is not working as expected, since there is an annoying space between that form group and the right side of the panel, that I've been trying to eliminate and I have not been able to do it. </p>
  
  <p><img src="https://i.stack.imgur.com/1HJCP.png" alt="White space beside the box that contains the 30"></p>
  
  <p>What I want to do is simply to eliminate that whitespace. I want the label and the textbox, as a group, to be right aligned in the panel.</p>
  
  <p>Can anyone tell me what I'm doing wrong?</p>
