Today I noticed a new feature that I’ve been waiting for for quite a long time. It was already possible to customize forms on lists but now it is also possible to customize forms on SharePoint document libraries.
As said it was already possible for quite a while to do this on lists but so far document libraries didn’t offer this option and we had to use the out of the box forms.
All you have to do is select the Customize forms option and you can make your changes to the forms.
This now means that it is possible to pull in information from other datasources and use them on your forms straight from your document library new and edit forms.
