Highlight current taxonomy menu

Hi guys,

I have deleted the default WordPress menu (no need for it on the site) and implemented a Category/Taxonomy menu. I am making use of the default WordPress categories to generate the menu.

I have the following code:

<?php
	# Navigation Taxonomy Menu ---> so dynamic it's unbelievable!
	$mylinks = get_terms('category', array(
		'parent' => 0,				# display parent category links only
		'orderby' => 'name',
		'hide_empty' => 0
		)
	);
	$count = count($mylinks);

	if ( $count > 0 ) {				# From the above, we create a menu
		foreach ( $mylinks as $mylink ) {
			$i++;
			echo '<li class="page_item-' . $i . '">'; 		// add incrementing value to id page
			# get current webdirectory and link to taxonomy menus
			echo '<a href=' . network_site_url() . '/' . $mylink->slug . ' class="'. $mylink->slug .'" >';
			echo $mylink->name;
			echo "</a>";
			echo "</li>";
			}
		}
?>

The menus are generated fine and work and group the categories as expected.

My only problem is that I cannot highlight the current selected category using CSS. This is how the html code looks:

<nav class="clearfix">
	<ul class="menu clearfix">
		<li class="page_item-1">
			<a href=https://localhost/Traderzone/alcohol class="alcohol" >Alcohol</a>
		</li>
		<li class="page_item-2">
			<a href=https://localhost/Traderzone/snacks class="snacks" >Snacks</a>
		</li>
		<li class="page_item-3">
			<a href=https://localhost/Traderzone/steak class="steak" >Steak</a>
		</li>
	</ul>
</nav>

How will I get to intergrate a “active” id to add some css? jQuery or can it be done within php?
