Walkthrough: Using a query to render items


Specify a query to run on a current context item

This walkthrough describes how to create a rendering variant for a blog post that renders the related products and all its child items. We will use rendering variants with a query item to accomplish this. This walkthrough also describes a more complex scenario of how to display a list of authors that share the same tag as the blog post.

The starting point for this walkthrough is the same as the scenario described in the Creating a rendering variant for a blog post walkthrough. To execute the step described for this scenario, you need an additional product list and tags.

The scenario

This scenario includes the following:

  • A site that contains blog posts.

  • A product list.

    Different product variants in the content tree.
  • A page template that refers to the product list using a query:

    Page template assigned by using a query.
  • The blog pages have the related products selected from a list:

    Related products assigned.
  • The author template inherits the _taggable base template:

    Base template taggable inherited.
  • The blog posts and the authors have tags assigned from a list:

    Authors and their assigned tags.
    Blogs and their assigned tags.

This walkthrough describes how to:

To be able to display a list of related products on every blog post, we will first create a rendering variant for the Page Content rendering:

  1. In the Content Editor, navigate to Presentation/Rendering Variants, right-click Page Content, and click InsertVariant Definition.

  2. Enter Related Products and click OK.

  3. Next, to create a title field, right-click the Related Products variant, click Insert, click Text, enter Title, and click OK

  4. In the Variant Details section, in the Tag field, select h3 and in the Text field, enter Related Products.

    Rendering variant for the Page Content rendering.

Next, we will create a rendering variant reference item that goes to the RelatedProducts field of the blog post, and renders the content of that field. A rendering variant reference item displays a field from a referenced item. If you want to display a field from a referenced item, you can define this field in the Pass through field field.

To create a rendering variant reference item:

  1. Right-click the Related Products variant, click Insert, click Reference, enter RelatedProducts, and click OK

    The Pass through field field defines the name of the field from the nested item. The rendering variant now passes through the Related Products field.

  2. To list the products by their title, right-click the Related Products variant, click Field, enter Title, and click OK.

  3. In the Variant Details section, in the Tag field, select h4.

    If you now add the Page content variant to the blog page, it will look like this:

    Page Content variant on the page.

    The reference passes through the RelatedProducts field and renders the content:

    Related products field.

To be able to list the product's child items, if there are any, let's use a query.

To add the query child item to a rendering variant:

  1. Right-click Related Products variant, click Query, and click OK.

  2. In the Variant Details section, in the Query field, add a query that searches for all children but leaves out the title: query:./*[@@templatename!='Page Data']

    If you now add the Page content variant to the blog page, it will look like this:


    The query passes through the Product list and renders the content: Product 1 with three variants and Product 2 with no variants.

  3. To add a dividing line between the different products, right-click Related Products variant, click HTML Tag, enter Line, and click OK.

  4. In the Variant Details section, in the Tag field, select hr.


You can build more complex queries. For example, if you want to run a query on authors with similar tags.

In this scenario, the blog pages and the authors contain tags.




If you want to execute the scenario as described in this walkthrough, you must make sure the Author template inherits the SXA _Taggable base template. 


And inherits the template:


For this example, we will build a query to list all authors that have a similar tag as a blog post page.

To create a query item that uses a token:

  1. In the Content Editor, navigate to Presentation/Rendering Variants, right-click Page Content, and click Insert, Variant Definition.

  2. Enter Authors with similar interest and click OK.

  3. Right-click Authors with similar interest  variant, click Field, enter Title, and click OK.

  4. Right-click Authors with similar interest variant, click Query,  enter Query for authors and click OK.

  5. In the Query field, click Build Query.

  6. In the Build Search Query dialog box, first search for the Authors' template: Enter template, and Authors.

  7. You can scope your search by adding the default SXA token: TaggedWithAtLeastOneTagFromCurrentPage|SxaTags

  8. The variant also needs a Header Wrapper that contains the fields to display for the author. For example add fields for the First Name, the Last Name, and the Picture:

  9. If you now add the rendering variant to blog post 1, all the authors that have the same tag as blog post 1 - Management- will be listed:
