我有 vertnav/left.phtml 文件代码,
<div class="vertnav-container">
<div class="">
<h4 class="no-display"><?php echo $this->__('Category Navigation:') ?></h4>
<?php $store_categories = $this->toLinearArray($this->getStoreCategories()) ?>
<?php if ($count = count($store_categories)): ?>
<ul id="vertnav">
<?php endif; ?>
<?php foreach ($store_categories as $i => $_category): ?><?php $class = array() ?>
<?php if ($count == 1): ?>
<?php $class[] = 'only' ?>
<?php elseif (! $i): ?>
<?php $class[] = 'first' ?>
<?php elseif ($i == $count-1): ?>
<?php $class[] = 'last' ?>
<?php if (isset($store_categories[$i+1]) && $this->isCategoryActive($store_categories[$i+1])) $class[] = 'prev'; ?>
<?php if (isset($store_categories[$i-1]) && $this->isCategoryActive($store_categories[$i-1])) $class[] = 'next'; ?>
<?php echo $this->drawOpenCategoryItem($_category, 0, $class) ?>
<?php endforeach ?>
<?php if ($count): ?>
</ul>
<?php endif; ?>
</div>
</div>
并根据我的要求将 System > Configuration > Catalog > Category Vertical Navigation 设置为 2,但现在鼠标悬停在显示的类别子类别上时应该显示
那么我该如何对其进行自定义并为此添加悬停效果代码呢?
请帮我
