Creating Collections from SharePoint Lists in PowerApps

Introduction to collections in PowerApps

Collections in PowerApps let you keep data within your app, handy for times when users are offline or have a weak connection. SharePoint lists have some restrictions on the queries you can run. With collections, you can run more complicated queries, mix data from different places, and add custom business rules easily.

Now we will see how to create a PowerApps Collection from the SharePoint list.

1. Collect: This is the PowerApps function name used to create a collection.
2. Collection Name: The name of the collection that the user will create.
