分類鏈接導航
根據後臺分類生成的導航鏈接在header區塊
page.xml
-------------------------------------
<block type="page/html_header" name="header" as="header">
<block type="page/template_links" name="top.links" as="topLinks"/>
<block type="page/switch" name="store_language" as="store_language" template="page/switch/languages.phtml"/>
<block type="core/text_list" name="top.menu" as="topMenu" translate="label">
<label>Navigation Bar</label>
</block>
<block type="page/html_wrapper" name="top.container" as="topContainer" translate="label">
<label>Page Header</label>
<action method="setElementClass"><value>top-container</value></action>

top.menu區塊
模板header.phtml
-----------------------------------------
<div class="header-container">
<div class="header">
<?php if ($this->getIsHomePage()):?>
<h1 class="logo"><strong><?php echo $this->getLogoAlt() ?></strong><a href="<?php echo $this->getUrl('') ?>" title="<?php echo $this->getLogoAlt() ?>" class="logo"><img src="<?php echo $this->getLogoSrc() ?>" alt="<?php echo $this->getLogoAlt() ?>"

<?php else:?>
<a href="<?php echo $this->getUrl('') ?>" title="<?php echo $this->getLogoAlt() ?>" class="logo"><strong><?php echo $this->getLogoAlt() ?></strong><img src="<?php echo $this->getLogoSrc() ?>" alt="<?php echo $this->getLogoAlt() ?>" /></a>
<?php endif?>
<div class="quick-access">
<?php echo $this->getChildHtml('topSearch') ?>
<p class="welcome-msg"><?php echo $this->getWelcome()?></p>
<?php echo $this->getChildHtml('topLinks') ?>
<?php echo $this->getChildHtml('store_language') ?>
</div>
<?php echo $this->getChildHtml('topContainer'); ?>
</div>
</div>
<?php echo $this->getChildHtml('topMenu') ?>
=======================================================
在catalog.xml重新定義
--------------------------------------------------------
<reference name="top.menu">
<block type="catalog/navigation" name="catalog.topnav" template="catalog/navigation/top.phtml"/>
</reference>
========================================================================
引入模板top.pthml
app\design\frontend\base\default\template\catalog\navigation\top.phtml
----------------------------------------
<?php $_menu = $this->renderCategoriesMenuHtml(0,'level-top') ?>
<?php if($_menu): ?>
<div class="nav-container">
<ul id="nav">
<?php echo $_menu ?>
</ul>
</div>
<?php endif ?>
=========================================================
renderCategoriesMenuHtml(0,'level-top') 加入了樣式後的<li class="level0 nav-1 level-top first parent">
app\code\core\Mage\Catalog\Block\Navigation.php 裏定義 renderCategoriesMenuHtml（），調用_renderCategoryMenuItemHtml()，函數裏寫的<li><span>標籤和樣式名。
