    Readonly fields are only available on the display form, not on the New and Edit forms.
    Actually this is the same as on SharePoint standard forms. This also applies for example for SharePoint calculated columnns. I assume the main reason Microsoft implemented it like this is that these fields are not automatically updated in the form when the lookup is changed. This would confuse users.

    An alternative using Rich Forms is to add columns to the list and use calculated value expressions like [[Lookup.SomeField]] to dynamically set these fields when the Lookup column is changed. This would make the field automatically show the updated value in the form when editing the Lookup.

    Yes I have been working how to set the calculated value. Where can I see the manual/sample about the usage of "Lookup"?

    In the documentation there is some information on the available placeholders: skybow SharePoint Apps
    In the expression builder you will also find a tree to the left with possible placeholders. If you expand the appropriate lookup field the possible fields of the list are shown. Double-clicking on the field you want will insert the placeholder in to the expression.
