<h1>jQuery Traversing Ancestors - <code>parent()</code> Method</h1>
		<p>Click any list item below. Only when its immediate <code>ul</code> parent matches the selector <code>ul.food-list</code> will that container highlight, demonstrating how the optional selector filters the result.</p>

<div class="wrapper">
			<ul class="food-list" id="foodList">
				<li>Pizza</li>
				<li>Burger</li>
				<li>Sushi</li>
			</ul>

<ul class="drink-list" id="drinkList">
				<li>Tea</li>
				<li>Coffee</li>
				<li>Juice</li>
			</ul>
		</div>

<div class="info" id="infoBox">Click an item to test <code>parent('ul.food-list')</code>.</div>

// Get immediate parent filtered by 'ul.food-list'
					var $foodParent = $(this).parent('ul.food-list');

if ($foodParent.length) {
						$foodParent.addClass('highlight');
						$('#infoBox').text('Matched parent container: #' + $foodParent.attr('id'));
					} else {
						$('#infoBox').text('No match: parent is not ul.food-list.');
					}
				});
