wait for all jQuery animations to complete then make the newly expanded section can be seen in the viewport

jQueryAnimateDone.js

$container = $('myElem');

$(":animated").promise().done( function() {
	if( $container[0].getBoundingClientRect().top < 50 ) {
		$('html,body').animate({scrollTop: $container.offset().top}, 800);
	};
});
