The Form Preview is simply a visual representation of what the Form would look like in the SpatialWorx app, but without any data in the fields.
It is not intended to be a working form for entering data or testing but shows the basic layout of the fields, pages, and other elements of the form.
Subforms cannot be previewed due to data dependencies that aren't available in preview mode.
As changes are made to the settings and characteristics of the form (fields added, labels updated, etc.) those changes are dynamically reflected in the
Form Preview.
The Group Update View switch depicts what the form would look like when editing a group of feature attributes together using the group update
function in the SpatialWorx app.
