navbar-right contents side by side
<p>I've a top fixed bootstrap navbar, where on left there is a brand and on right side there is a combo-box and a navbar form.But the problem is that the right contents are overflowing on top of each other. I want them right next to each other.Combo-box should come first and then the form.
Here is the screenshot:</p>

<pre><code>&lt;nav class="navbar navbar-inverse navbar-fixed-top"&gt;
        &lt;div class="container"&gt;
            &lt;div class="navbar-header"&gt;
                &lt;a class="navbar-brand" href="#"&gt;
                    &lt;img alt="Brand" src="img/nice.png" width="100" height="100"&gt;
                &lt;/a&gt;
            &lt;/div&gt;
            &lt;div class="links navbar-right"&gt;
                &lt;!-- Split button --&gt;
                &lt;div class="btn-group"&gt;
                &lt;button type="button" class="btn btn-default"&gt;Action&lt;/button&gt;
                &lt;button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"&gt;
                &lt;span class="caret"&gt;&lt;/span&gt;
                &lt;span class="sr-only"&gt;Toggle Dropdown&lt;/span&gt;
                &lt;/button&gt;
                &lt;ul class="dropdown-menu"&gt;
                    &lt;li&gt;&lt;a href="#"&gt;Action&lt;/a&gt;&lt;/li&gt;
                    &lt;li&gt;&lt;a href="#"&gt;Another action&lt;/a&gt;&lt;/li&gt;
                    &lt;li&gt;&lt;a href="#"&gt;Something else here&lt;/a&gt;&lt;/li&gt;
                    &lt;li role="separator" class="divider"&gt;&lt;/li&gt;
                    &lt;li&gt;&lt;a href="#"&gt;Separated link&lt;/a&gt;&lt;/li&gt;
                &lt;/ul&gt;
                &lt;/div&gt;
                &lt;form class="navbar-form" role="search"&gt;
                    &lt;div class="input-group"&gt;
                        &lt;input type="text" class="form-control" placeholder="Search for..."&gt;
                        &lt;span class="input-group-btn"&gt;
                        &lt;button class="btn btn-default" type="button"&gt;Go!&lt;/button&gt;
                        &lt;/span&gt;
                    &lt;/div&gt;
                &lt;/form&gt;
            &lt;/div&gt;
        &lt;/div&gt;
    &lt;/nav&gt;
