Setting default selection in dropdown list

Yup, just set the value field to the one you want selected by default — in this case it acts as the “default value” for that field.

Note: it must match the “value” part of your choices (if you have a different value/label).

e.g.

1|2|3|4
Value: 2

1:One|2:Two|3:Three
Value: 2

One|Two|Three
Value: Two
