Using forms in classic SharePoint mode


I am using Forms to create forms for SharePoint but I want them to be in classic view.

How do I use forms to create classic forms?
Can I create a SharePoint form but publish it like the Plumsail (public) forms on a SharePoint page?


Dear Marion,

Forms is the product that is designed from the ground up to work with Office365 and its Modern UI, thus the forms doesn’t support Classic UI and will be open in Modern UI even on the classic site.

SharePoint Forms can be added through Classic UI:

We’ll add a web part for SharePoint Forms in the future.
