By right-clicking on the "Form Structure" region, you can add a new root group node (Group nodes are like "Regions" in APEX, they group different nodes together, nodes are like APEX Page Items. They are form inputs).
In the node properties tab, you define the different properties you want your nodes to have, for example, Label, (Unique) Name, Node type, List of Values...
On the right, you can view the rendered Form. This is based on the form structure and the node properties you defined.

You can define new Reusable lists in the top right corner, reusable lists are lists you define that can be used in any form you like. Much like APEX "Shared components" > "List of Values".

After saving you will see the regions update, after this you can right click other "Group" nodes to add children to this group.

When you are happy with your form, you can use the "Publish" button to make a version of the form you can use in other applications and send to your users.
