Custom block: make marks property for writer field dynamic in Vue template

So, I have (re-)created the custom FAQ block with editable previews and I noticed that the marks properties for the writer fields are static in the Vue template. How can I make them dynamic as in the preview for the accordion block?

I’m not very experienced with Vue; I’ve tried:

  @input="updateItem(content, index, 'details', $event)"

but that didn’t do anything, so I suppose something must be added to the computed property of the Vue object to loop through the faq items and get the fields. Can anybody help me? :frowning:
