There are two ways to do this:

CSS

Add the following CSS to the Advanced Settings Main Element of the first accordion item. This should be an ’empty’ item which will not be displayed at all:

display: none;Code language: HTTP (http)

jQuery

The alternative is to add the following jquery to a code module on the same page or to the footer.

<script>
jQuery(function($){
    $('.et_pb_accordion .et_pb_toggle_open').addClass('et_pb_toggle_close').removeClass('et_pb_toggle_open');

    $('.et_pb_accordion .et_pb_toggle').click(function() {
      $this = $(this);
      setTimeout(function(){
         $this.closest('.et_pb_accordion').removeClass('et_pb_accordion_toggling');
      },700);
    });
});
</script>Code language: HTML, XML (xml)
