title: PrimeNG: Align listbox and panel next to each other
body: <p>I use PrimeNG Beta 17 integrated in my Angular 2 app.
  Within my template I want to place a listbox next to a panel, whereas the listbox shall appear left to the panel.</p>
  
  <pre><code>&lt;p-listbox [options]="modelTypes" [(ngModel)]="selectedModelType"
             [style]="{'width':'150px','max-height':'150px'}"&gt;&lt;/p-listbox&gt;
  &lt;p-panel header="Model description" [toggleable]="true" [collapsed]="true" &gt;
            Lorem ipsum dolor sit 
  &lt;/p-panel&gt;
  </code></pre>
  
  <p>Any idea how to accomplish this?
  I am aware of the "float" technique in CSS, however I wonder if there is any built-in support in PrimeNG to ease layouting.</p>
