How to Sort Checked and Unchecked list item in Material Ui Autocomplete List

Question

I have been learning Material Ui and going through its documentation. I came across an exciting Material Ui component named "Autocomplete". I have been going through Autocomplete component Checkbox demo Example code.

I need help to bring all the selected items at top of the list of the drop-down. The items are getting selected and are shown in the text field, But I also want those selected items to be present at the top of the dropdown list.

Here is the link to the code of a checkbox, I got through Material UI documentation: https://codesandbox.io/s/8gbef?file=/demo.js enter image description here
