Cascade Dropdow

Hi Team!

I follow this article https://plumsail.com/docs/forms-sp/how-to/lookup-cascading.html. I created first and second list according to instruction. Also I created third list and need to change Extra Fields property and Expand property. However I cannot see settings field in the right part of forms designer. I see only FIELD, LAYOUT, TITLE, CONTROL and that's all. I use version for development. Could you please assist what can be the reason?

Thank you.

@SkillMary,

Have you created the lookup field?

Please check the field type. You can see the field type in the designer.
