title: bootstrap dropdown menu items size not changing
body: <p>I have one more problem with bootstrap navbar dropdowns</p>
  
  <p>this is my code</p>
  
  <pre><code>&lt;header class="navbar navbar-purple navbar-static-top bs-docs-nav" role="banner"&gt;
      &lt;div class="container"&gt;
          &lt;div class="navbar-header"&gt;
              &lt;button class="navbar-toggle" type="button" data-toggle="collapse" data-target=".bs-navbar-collapse"&gt;
                  &lt;span class="sr-only"&gt;Toggle navigation&lt;/span&gt;
                  &lt;span class="icon-bar"&gt;&lt;/span&gt;
                  &lt;span class="icon-bar"&gt;&lt;/span&gt;
                  &lt;span class="icon-bar"&gt;&lt;/span&gt;
              &lt;/button&gt;
              &lt;a class="navbar-brand" href="http://pos.shalvasoft.tk/"&gt;&lt;span class="first"&gt;ShalvaSoft&lt;/span&gt; &lt;span class="second"&gt;POS&lt;/span&gt;&lt;/a&gt;
          &lt;/div&gt;
          &lt;nav class="collapse navbar-collapse bs-navbar-collapse" role="navigation"&gt;
              &lt;ul class="nav navbar-nav navbar-right"&gt;
                  &lt;li class="dropdown langs"&gt;
                      &lt;a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false"&gt;
                          &lt;span class="caret"&gt;&lt;/span&gt;
                          &lt;span id="selectedlang"&gt; &lt;i class='flag-icon flag-icon-ge'&gt;&lt;/i&gt;&lt;/span&gt;
                      &lt;/a&gt;
                      &lt;ul class="dropdown-menu" role="menu"&gt;
                          &lt;li class="hidden"&gt;&lt;a href="#" class="lang" data-link="ge"&gt;&lt;i class='flag-icon flag-icon-ge'&gt;&lt;/i&gt;&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a href="#" class="lang" data-link="ru"&gt;&lt;i class='flag-icon flag-icon-ru'&gt;&lt;/i&gt;&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a href="#" class="lang" data-link="en"&gt;&lt;i class='flag-icon flag-icon-us'&gt;&lt;/i&gt;&lt;/a&gt;&lt;/li&gt;                    &lt;/ul&gt;
                  &lt;/li&gt;
                  &lt;li class="dropdown langs"&gt;&lt;a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false"&gt;&lt;img src="http://pos.shalvasoft.tk/public/image/users/1_thumb.jpg" height="20px" width="20px"&gt; &lt;span class="caret"&gt;&lt;/span&gt;&lt;/a&gt;&lt;ul class="dropdown-menu" role="menu"&gt;&lt;li&gt;&lt;a href="http://pos.shalvasoft.tk/logout"&gt;logout&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt;&lt;/li&gt;            &lt;/ul&gt;
          &lt;/nav&gt;
      &lt;/div&gt;
  &lt;/header&gt;
  </code></pre>
  
  <p>now in the css I have this rulers</p>
  
  <pre><code>.navbar-purple .navbar-nav &gt; li:not(.langs) .dropdown-menu{width:118px !important;}
  .navbar-purple .navbar-nav &gt; li:not(.langs) .dropdown-menu &gt; li{width:118px !important;}
  .navbar-purple .navbar-nav &gt; li.langs .dropdown-menu{min-width:63px !important;}
  .navbar-purple .navbar-nav &gt; li.langs .dropdown-menu &gt; li{width:63px !important;}
  </code></pre>
  
  <p>As you see I need to add on clas langs and it`s childs 63px width
  and on others I need to add default size or 118px.
  but this code not working
  see the images</p>
