看起來像這樣，但我希望“Hapjes”中的所有資訊都進入 1 個“Hapjes”類別，而不是分開。
uj5u.com熱心網友回復：
我認為您想要實作的目標可以通過regrouptemplate tag來完成。
{% regroup mygerecht by categorie as article_categories %}
{% for categorie in article_categories %}
<div class="flex">
<div class="menu-head center">
<h2>{{categorie.grouper}}</h2>
</div>
{% for article in categorie.list %}
<div class="menu-item">
<ul class="price">
<li>{{article.gerecht_name}}</li>
<li>€{{article.gerecht_price}}</li>
</ul>
<p>{% if article.gerecht_description %}{{article.gerecht_description}}{% endif %}</p>
</div>
{% endfor %}
</div>
{% endfor %}
