Hi Christoph,
Thank you for contacting us and I'd be happy to assist.
You can use a Toolset post view to show an accordion, with data coming from a repeating field group.
( example of the accordion: versteckter Link )
Here are the steps:
1. Please make sure that "Toolset should load Bootstrap 4" options is selected at WP Admin -> Toolset -> Settings -> General.
2. Next, you'll add a repeating field group, for the post in which you'd like to show the accordion. In this case, I'm using the post "Project" as an example.

3. Each accordion item will need to have two fields, title, and the content, so you'll add a single line type field for the title and a WYSIWYG field for the content in this new repeating field group

4. These fields will show on each Project post's edit screen so that the client can add as many accordion items as needed.

5. To show this data on the front-end in an accordion, you'll create a new post view and set it to get results from this new repeating field group.

6. Since your goal is to show accordion from only those items which are added with the post that is being viewed, you'll add a query filter, with an option: "The post where this View is shown".

7. In the "Loop Editor" section, you'll add the content wrapped in an accordion container:
( screenshot: versteckter Link )
[wpv-layout-start]
[wpv-items-found]
<div class="accordion" id="accordionProject">
<!-- wpv-loop-start -->
<wpv-loop>
[wpv-post-body view_template="loop-item-in-view-to-show-project-accordion"]
</wpv-loop>
<!-- wpv-loop-end -->
</div>
[/wpv-items-found]
[wpv-no-items-found]
<strong>[wpml-string context="wpv-views"]No items found[/wpml-string]</strong>
[/wpv-no-items-found]
[wpv-layout-end]
Note: Please replace "loop-item-in-view-to-show-project-accordion" with the actual slug of your view's content template.
8. In the view's template, you'll add the code for each accordion item, along with the custom fields shortcode like this:
( screenshot: versteckter Link )
<div class="card">
<div class="card-header" id="heading-[wpv-post-id]">
<h2 class="mb-0">
<button class="btn btn-link" type="button" data-toggle="collapse" data-target="#collapse-[wpv-post-id]" aria-expanded="true" aria-controls="collapse-[wpv-post-id]">
[types field='accordion-item-title'][/types]
</button>
</h2>
</div>
<div id="collapse-[wpv-post-id]" class="collapse" aria-labelledby="heading-[wpv-post-id]" data-parent="#accordionProject">
<div class="card-body">
[types field='accordion-item-content'][/types]
</div>
</div>
</div>
Note: Please replace "accordion-item-title" and "accordion-item-content" with the actual slugs of your title and content fields.
9. As a result, when you'll insert this newly created view's shortcode inside any Project post, it will show an accordion, from items added with that post.

I hope this helps and please let me know if you need any further assistance around this.
