iTunes Select the iPad, click Applications, and in the virtual screen below, drag an icon to another icon, and a grouping box will pop up to name it. Click on the blank space to complete and put the same type into a group.
You can also go directly to iPad 2 without connecting to itunes. Press and hold an icon without moving. When they all start to shake, drag an icon to another software of the same type and a group will be created. Name it and drag other similar software here.
