Why i'm losing the navigation menu when i get my site by mobile ?
Do i need something else than those :
<!-- Include the Grid css file -->
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<link type="text/css" rel="stylesheet" href="assets/framework/css/JFGrid.css" />
<!-- Include the Menu css files -->
<link type="text/css" rel="stylesheet" href="assets/framework/css/menus/JFMenu.css" />
<link type="text/css" rel="stylesheet" href="assets/framework/css/menus/JFMenuStyle-4.css" />
