I have two List selection controls on a screen, one is “Region” and the other is County". When a region is selected from the region List selection I want to only display Counties in the Counties List selection that are in the region that is selected. See attached pic. is this possible? I am not using the latest version of Flow Studio (6.4). I am on an earlier version. ![Counties](https://europe1.discourse-cdn.com/flex013/uploads/novacuratalk/original/1X/55dcf8ab1dd656cce98f5282fcb01c8d6b37364b.png) ---

We accomplish this with a two column data grid (both value lists) where the second column’s table expression includes a where clause which is based on the first column’s value. I don’t know if there is another way to do it in flow without a datagrid. ---

Thanks for the reply but I don’t want to use a data grid, it has to be two List controls. ---

Hi, as mentioned,we cant connect 2 lists in the same element. As a workaround we sometimes place a refresh button. Then after refresh we loop back and filter available options in list 2 based on selection in list 1. Here is an example: ![grafik](https://europe1.discourse-cdn.com/flex013/uploads/novacuratalk/original/1X/e6b363eb56c7f7f3b70a511d0100eb9f7762a652.png) ![grafik](https://europe1.discourse-cdn.com/flex013/uploads/novacuratalk/original/1X/a81a75953557971cfd5e372e37503ca5078769fc.png) Also example flow here: [https://novacura-my.sharepoint.com/:u:/p/ivan\_stojiljkovic/EZIoe3WiHdVOo1HkaK9WLpABbRdAE54R7OYh3hVMQ6CZng?e=djdPCO](https://novacura-my.sharepoint.com/:u:/p/ivan_stojiljkovic/EZIoe3WiHdVOo1HkaK9WLpABbRdAE54R7OYh3hVMQ6CZng?e=djdPCO) Hope this helps!
