Bottom Category on left navigation is always open

Question

I have a problem on my product categories page the navigation that we have going down the left side displays all the categories we need it to and also it bold a subcategory when you are on it, However when you are not on any sub categories and you are on the main categories page The bottom category is always in bold even when you are not on it.

This is my code which creates the navigation (this is a .phtml file)

<?php
ob_start();

$store_categories = $this->getLeftCategories();
if ($count = count($store_categories)) {

$block_title = $this->getBlockTitle();
if ( empty($block_title) ) $block_title = 'Categories';
?>
<div class="block block-left-nav">
    <div class="block-title">
        <strong><span><?php echo $this->__($block_title) ?></span></strong>
    </div>
    <div class="block-content">
        <ul id="left-nav">
        <?php
        $i=0;
        foreach ($store_categories as $_category) {
            $class = array();
            if (!$i) {
                $class[] = 'first';
            } elseif ($i == $count) {
                $class[] = 'last';
            }
            echo $this->drawOpenCategoryItem($_category, 0, $class);
            $i++;
        } ?>
        </ul>
    </div>
</div>
<?php
} 
// if ($count = count($store_categories)) {
$mdms_blocks = Mage::registry('mdms_blocks');
if ( !$mdms_blocks ) {
    $mdms_blocks = array();
} else {
    Mage::unregister('mdms_blocks');
}
$mdms_blocks['block_left_nav'] = ob_get_clean();
Mage::register('mdms_blocks', $mdms_blocks);

I assume that what opens the categories is the drawOpenCategoryItem function

This is the code in the navigation.php which has that function in it but i cant see anything wrong.

If you can see anything which maybe causing this problem could you let me know please as i am lost with this problem.

Thank you

Answer 1

This could be a CSS related issue, please try to find the exact CSS being used for that block and try to see if any Bold font design has been written over there!

Answer 2

Maybe you're just getting this active class through some JavaScript code on frontend? I would start from checking all JavaScript related to the menu.
