How to create a Collection from your Selection in Power Apps

In Power Apps, creating a collection based on a selection allows you to store and manipulate a set of items chosen by the user. This is typically done by using the Collect() function in response to an event, such as selecting an item in a gallery or selecting multiple items in a gallery. This can be extremely useful when you want to manipulate or view certain data.

There are some extremely useful topics you will learn:
1. How to AddColumn to a Datasource in a Collection
2. How to Add a Checkbox to a Gallery and Save the Data
3. How to Create a Collection Based on those Checkboxes

Below are formulas we used in this video:
