With
Power Apps, you cannot only create and modify apps but also
customize forms used for SharePoint list items.
In the demo below, Peter Kalmström, CEO and Systems
Designer of kalmstrom.com Business Solutions, shows how
to customize SharePoint list forms in Power Apps. The form
he creates will be applied to all forms in the list: Display,
Edit and New.
When the new Edit form opens in Power Apps, all columns
are not included, so Peter adds them via Edit fields. He
also distributes the fields in two columns and make some
of them fill the whole widht.
