Multiple check box

I'm have a scenario.

"MyField" has 4 check box options. It allows user to select multiple check boxes.

- Checkbox1

- Checkbox2

- Checkbox3

- Checkbox4

How can I enable user to select 1 or up to 4 options and store the values in "MyField"

When retrieved MyField, it shows "Checkbox1", "Checkbox2", "Checkbox3", "Checkbox4"

Is this possible?
