Rendering popup menu on page load

I’m using introJS to create a demo and in order to demo the popup of a menu, I need to use

menu.callEvent("onMouseMove",[id,null,menu.getItemNode(id)]);
    menu.callEvent("onMouseOut",[id,null,menu.getItemNode(id)]);

As soon as the page loads, otherwise introJs doesn’t register it. Is there a way to make the component popup render on page startup?
