1. Crie um Dynamic Action - PAGE LOAD.
2. Quando TRUE, Execute JavaScript code. Use esse código:
(function($) {
$(window).on('theme42ready', function() {
/* Make sure that the navigation menu is collapsed on page load */
if ($('.t-PageBody').hasClass('js-navExpanded')) {
$('#t_Button_navControl').click();
}
/* Expand on mouse over, collapse on mouse out */
$('.apex-side-nav .t-Body-nav').hover(
function(){
//only expand if the side menu is collapsed
$('.t-PageBody:not(.js-navExpanded) #t_Button_navControl').click();
},
function() {
$('#t_Button_navControl').click();
}
);
});
})(apex.jQuery);
