The problem with selectors

Question

The problem I am facing is not able to select divs inside the div'a menuItem. I tried using the jQuery selector to select both for the class and for the ID, but every time I try to do something with it, such as animation, nothing happens. Is there any jQuery law that I don't know about that prevents me from doing this?

$('.menu')
    .hover( function() { 
        $(this).toggleClass('highlighted'); 
    })
    .click(function() {
        $(this).parent().children('.menuItem').children('#wtf').slideDown();
    });

Also tried this for click (), but none of them work.

$('#wtf').slideDown();
$('.test').slideDown();
$(this).parent().find('.menuItem').each( function() { $(this).slideDown(); } );
$(this).parent().children('.menuItem').children().slideDown();

Answer 1

I applied the background color to your style and your jQuery selector was not selected correctly. I tried this, and it changed the background color, but I don’t have CSS to render slideDown () work - you will need to write your CSS correctly.

$().siblings() ( "# WTF" ) CSS ( " ", "# CCCCCC" ) slideDown();...

$(this+' > .menuItem div')
