Element grouping feature

Are there any in-depth demos of the Element grouping features? I was only able to find a short video with no audio on Youtube.

Hello,

Campaign creation and usage for elements group is documented there: Element group - Callico

It basically support:

  1. creating a range of tasks for multiple users on images spanning multiple pages
  2. users can create groups (such as paragraphs) and set any number of child element (such as text lines)

We built this mode to annotate newspapers, grouping lines into articles.
