<pre><code>&lt;ion-side-menus enable-menu-with-back-views=&quot;true&quot;&gt;
&lt;ion-side-menu-content&gt;
    &lt;ion-nav-bar class=&quot;bar-dark&quot;&gt;
        &lt;ion-nav-back-button&gt;
        &lt;/ion-nav-back-button&gt;      
        &lt;ion-nav-buttons side=&quot;left&quot;&gt;
            &lt;button class=&quot;button button-icon button-clear ion-navicon&quot; menu-toggle=&quot;left&quot;&gt;&lt;/button&gt;
        &lt;/ion-nav-buttons&gt;
        &lt;ion-nav-buttons side=&quot;right&quot;&gt;
            &lt;button  class=&quot;button button-icon button-clear ion-log-out&quot; ng-click=&quot;logout()&quot;&gt;&lt;/button&gt;
        &lt;/ion-nav-buttons&gt;          
    &lt;/ion-nav-bar&gt;
    &lt;ion-nav-view name=&quot;menuContent&quot; style=&quot;background-color:red;&quot;&gt;   
    &lt;/ion-nav-view&gt;
&lt;/ion-side-menu-content&gt;
    &lt;ion-side-menu side=&quot;left&quot;&gt;
        &lt;ion-header-bar class=&quot;bar-dark&quot;&gt;
            &lt;h1 class=&quot;title&quot;&gt;Menu&lt;/h1&gt;
        &lt;/ion-header-bar&gt;
        &lt;ion-content&gt;
            &lt;ion-list&gt;
                &lt;ion-item menu-close href=&quot;#/app/dashboard&quot;&gt;
                    &lt;i class=&quot;icon icon-dashboard&quot; style=&quot;font-size:20px;margin-right:10px;&quot;&gt;&lt;/i&gt;
                    Dashboard
                &lt;/ion-item&gt; 
&lt;ion-item menu-close href=&quot;#/app/dashboard&quot;&gt;
                    &lt;i class=&quot;icon icon-dashboard&quot; style=&quot;font-size:20px;margin-right:10px;&quot;&gt;&lt;/i&gt;
                    Statistics
                &lt;/ion-item&gt;             
            &lt;/ion-list&gt;
        &lt;/ion-content&gt;
    &lt;/ion-side-menu&gt;
