Here is the code, I’m using in the theme and I want to be able to click once and the link
The Latest pulls up after click not for it to callback.
<script>
jQuery( "li#menu-item-28 a" ).click(function() {
jQuery( "div#the-latest.bg div.container" ).slideToggle( "slide" );
});
</script>
Im not sure that I understand your question but try:
event.preventDefault() prevents the default event which happens when the link is clicked.
