<nav class="navbar navbar-default navbar-fixed-top" role="navigation" style="margin-bottom:0px !important;">
  <div class="container">
    <div class="navbar-header">
      <a id="menu-toggle" (click)="show()" class="navbar-toggle">
          <span class="sr-only">Toggle navigation</span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
      </a>
      <a class="navbar-brand" href="home.xhtml">
        <img src="images/socialwiki.png">
      </a>
    </div>
    <div  *ngIf="hide" id="sidebar-wrapper"  class="sidebar-toggle">

      <ul class="sidebar-nav">
         <li>
              <a onclick="profilelink('login')"><i class="icon-signin"></i>login</a>
