Dynamics Portal: filter knowledge search results by category in same results page

Posted on by JasR

I have a requirement in Dynamics Portal to show knowledge articles search list that users can then filter by category. I'm want to achieve something similar to https://www.samsung.com/uk/support/model/SM-G991BZIGEUA/ where the left side bar contains categories that then dynamically filter the displayed articles list - all on same page.

I know this will be a custom page and can use FetchXML to get the articles and their categories but are not sure how to implement the filtering feature. Any help on how to achieve this (if possible including code) is greatly appreciated.

Thanks in advance.

RE: Dynamics Portal: filter knowledge search results by category in same results page

Hi JasR

Look at what is actually being done for the Customer Self Service. There are 2 main Web templates being utilised:

Knowledge Base - Home: this lists the categories and creates URLs that pass the category number to the child page

Category Details: this receives the category number in the id parameter, which is then used to end up getting the GUID of the actually category (this is then substituted into the FetchXML query to retrieve the collection of articles).

These are two pieces of code that involve categories as well as knowledge base articles, maybe you can refer it:

{% extends 'layout_1_column' %} {% block main %} {% include 'Page Copy' %} {% assign category_url = sitemarkers['Category'].url %} {% assign count = count | default: 0 %} {% assign categories = knowledge.categories | top_level: count %} {% if categories %}
{% for category in categories %} {{ category.title }} {% endfor %}
{% endif %} {% endblock %}

{% extends 'Layout 1 Column' %} {% block breadcrumbs %} {% assign categoryid = request.params['id'] %} {% if categoryid %} {% assign category = knowledge.categories | category_number: categoryid %} {% if category %} {% assign pagetitle = category.title %} {% assign categoryguid = category.categoryid %} {% else %} {% assign pagetitle = resx["Knowledge_Article_Unavailable"] %} {% endif %} {% endif%} {% include 'Breadcrumbs' title: pagetitle %} {% endblock %} {% block title %} {% include 'Page Header' title: pagetitle %} {% endblock %} {% block main %} {% include 'Page Copy' %} {% assign category_url = sitemarkers['Category'].url %} {% assign portallanguagecode = website.selected_language.code %} {% if categoryguid %} {% fetchxml knowledgearticlecategory_query %} {% if portallanguagecode %} {% endif %} {% endfetchxml %} {% assign articles = knowledgearticlecategory_query.results.entities %} {% if articles.size > 0 %}
{% for article in articles %}
{{ article.title | escape }}
{{ article.description | escape }}

{% endfor %}
{% endif %} {% include 'Category - Related Categories' categoryguid: categoryguid %} {% else %}

{% editable snippets "KnowledgeManagement/ArticleUnavailableMessage" %}

{% endif %} {% endblock %}
