NullFileldList is an option where we use it to nullify the variant which is not required by the user in the program. It is done using code. Now let's see a practical example; here we have to enter the address of a shipment, and it only has add1 and add2, city, state, but also has Add3. So when we simply add address(1 and 2) it says invalid address, here we can use NullFieldList code to remove Add3.

 

< nullFieldList >

 < name > attention < / name >

 < name > addr3< / name >

 < name > city < / name >

 < name > state < / name >

 < name > zip < / name >

 < / nullFieldList >
