Move the values in the list on the left to the right

Move the values in the list on the left to the right. for example, the values on the left are 1, 2, 3, 4, 5, and 6.
I chose 5, 3, 4.
Why is there 3, 4, 5 displayed on the page?

The right side is also sorted!
If you don't want to sort the data on the right, check the code to see if it can be removed.
