This is possible without using a macro. You will have to use INDIRECT and IF
of for this

here's how this will work
Assume that you have col A, B and C for 3 different teamleaders
in cell D1 you have TL name
in cell E1 you have team member drop down
now, for on the validation screen for cell E1 type =INDIRECT(Z1)
in cell Z1 type in IF formula such as =IF(D1="abc","A1:A20","B1:B20")
change the IF formula as per your need.

How does this work???

Depending on TL name selected a range constant will be stored in cell Z1
which represnts the list of team members
For the drop down validation INDIRECT will repturn this cell address and the
values in A1:A20 will be used.

hope this helps!!!

I am making a sheet where for example 'the cell A1 has a data validation
list' and depending on the selection in A1 cell the data validation list in
cell B1 will change.
for example:-cell A1 contains the list of team leaders depending on the
selection of the team leader from the list in A1 i should get a list of his
team members in cell B1.

Is that possible using data validation or do i need to use macros to get
that functionality. can anyone help me with that.
