As you design your forms, you may want to gather a number of controls into a logical group. While this is possible in Power Apps it is currently an Experimental feature. To enable the feature you need to navigate to App Settings | Advanced Settings and scroll down. Once activated you can select (using the Crtl button) multiple controls and then use Crtl+G to group them together. It will also add ‘Group’ to the Controls Menu. See Enhanced Group control in canvas apps enables more control over layout and nesting for more details.
