hi R's
Please someone help me in this situation,

your_list <- list(
    PERSON1 = list(
        group = "A,B,C",
        name = "PersonName1",
        age = 25
    ),
    PERSON2 = list(
        group = "X,Y,Z",
        name = "PersonName2",
        age = 28
    )
)

i would like to unwind the rows based on the column Group

the expected Result is as below
ID | name | group | age

PERSON1 | PersonName1 | A | 25
PERSON1 | PersonName1 | B | 25
PERSON1 | PersonName1 | C | 25
PERSON2 | PersonName2 | X | 28
PERSON2 | PersonName2 | Y | 28
PERSON2 | PersonName2 | Z | 28

Thanks in Advance
