title: Full width searchbar in navbar bootstrap
body: <p>I want to get a navbar with logo image at the left and some links at the right in two rows and in the middle I want a big search bar. I am using bootstrap 3.7.7. I managed to get the logo on the left and other links over the right but no luck with big search bar. I am using following code to achieve the same - </p>
  
  <pre><code>&lt;div class="navbar navbar-inverse navbar-fixed-top navcustom"&gt;
      &lt;div class="container-fluid"&gt;
          &lt;div class="navbar-header"&gt;
              &lt;button class="navbar-toggle" type="button" data-target=".navbar-collapse" data-toggle="collapse"&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="logo" href="#"&gt;
                  &lt;img class="img-responsive" src="~/img/finalogo.png" class="img-responsive"/&gt;
              &lt;/a&gt;
          &lt;/div&gt;
          &lt;div class="navbar-collapse collapse" id="searchbar"&gt;
              &lt;ul class="nav navbar-nav navbar-right"&gt;
                  &lt;li&gt;&lt;a href="about.html"&gt;About&lt;/a&gt;&lt;/li&gt;
                  &lt;li&gt;&lt;a href=""&gt;&lt;i class="icon-user"&gt;&lt;/i&gt; My Page&lt;/a&gt;&lt;/li&gt;
                  &lt;li&gt;&lt;a href="#loginform" data-toggle="modal"&gt;Login&lt;/a&gt;&lt;/li&gt;
              &lt;/ul&gt;
              &lt;ul class="nav navbar-nav navbar-right"&gt;
                  &lt;li&gt;&lt;a title="Start a new search" href="#"&gt;Clear&lt;/a&gt;&lt;/li&gt;
              &lt;/ul&gt;
              &lt;div class="form-group"&gt;
                  &lt;input class="form-control" type="text" placeholder="Search"&gt;
                  &lt;span class="input-group-btn"&gt;
                      &lt;button class="btn btn-default" type="button"&gt;
                          &lt;span class="glyphicon glyphicon-search"&gt;&lt;/span&gt;
                      &lt;/button&gt;
                  &lt;/span&gt;
              &lt;/div&gt;
          &lt;/div&gt;&lt;!--/.nav-collapse --&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
