I want to hide the div class "navmain2" if the menu is empty. See code below:

          <!-- Start main navigation -->

    <div class="navmain2">
<div id="logo"></div>

        <!-- Gets main menu by id -->
        <span></span>
            <?php wp_nav_menu( array(
            'menu' => 11,
            'container' =>false,
            'menu_class' => 'nav',
            'echo' => true,
            'before' => '',
             'after' => '',
             'link_before' => '',
             'link_after' => '',
             'depth' => 0,
            'walker' => new description_walker())
             );?>

        <!-- /main menu -->

  <div id="klicka">Click here! Click here! Click here</div>

    </div><!-- /main navigation -->-->

I have a logo and a div with text inside navmain2 as you can see.

The question is:

Is it possible to hide the whole navmain2 div if the wp_nav_menu is empty?

Assign the menu to a string:

$menu = wp_nav_menu(
    array (
        'echo' => FALSE,
        'fallback_cb' => '__return_false'
    )
);

if ( ! empty ( $menu ) )
{
    echo '<div class="navmain2">' . $menu . '</div>';
}

So should i edit the code or this is a seperate function that ill add in the same page ? –  M3o Jan 23 '13 at 23:47
    
@MeiasSafa Use it instead of your code at the same place. –  toscho Jan 24 '13 at 3:17
    
Cant get it to work. Because i have 2 divs in the main page. one called navmain and the other navmain2 and i just wanna hide navmain2 if it is empty. –  M3o Jan 28 '13 at 12:42
    
Its solved , thank you! –  M3o Jan 28 '13 at 14:36

Solution nr 2:

Is to hide the div thru Js.

$('#jqm-home').live("pagecreate", function() {
$(".navmain2").each(function() {
if($(this).children("ul").length == 0) {
$(this).hide();
}
});
});
