I have a very simple query. On a single form, I have two drop down fields and I want to make second drop down field values dependent of the first drop down field values. For example – If I have selected “Category 1” in first drop down list then I want to show “Category 1.1” and “Category 1.2” as the values available for second field and if I have selected “Category 2” in first drop down list then I want to show “Category 2.1” and “Category 2.2” as the values available for second dropdown field. P.S. I both the fields on a single object/entity.
