{% categoryList categories with moduleId="1" parentId="0" %}
    <ul>
        {% for item in categories %}
            <li>
                <a href="{{ item.Link }}">{{ item.Title }}</a>
            </li>
        {% endfor %}
    </ul>
{% endcategoryList %}

In this code block:

• {% categoryList categories with moduleId="1" parentId="0" %}This line of code tells AnQiCMS to get all top-level categories under the model with ID 1 (usually the article model), and assign these category data toparentId="0")categoriesVariable.
• {% for item in categories %}We continue to traversecategoriesThis collection, each loop will assign a category of data toitemVariable.
• <li><a href="{{ item.Link }}">{{ item.Title }}</a></li>In the loop body, we willitem.Linkas<a>label'shrefProperty,item.TitleAs link display text. In this way, each category is rendered as a clickable navigation item, which can be clicked to jump to the corresponding category page.
