How to create checkbox and validate from array list in angular js

I have a database of choices like (drinks,veg,nonveg) in comma separated I have taken this in array ["drinks", "veg", "nonveg"] and created a 3 checkbox in the user form using these value. If user has selected 2 value from this then it will store in user database. There I have an array of user validation [["drinks", "veg", "nonveg"], ["nonveg"]] ]1
