Cascading dropdown fields
0

Hi,

I have a category list and sub-category list and I want to create a two picker fields where the second one will be based on the first one.

Category(picker dropdown):
* A
* B

Sub-category(picker dropdown):
*A1
*A2
*B1
*B2

If I will choose Category A, the second picker field should show only A1 and A2 option.
How to achive it?
