Changing default value of uipath dynamic form

im passing the below list to a uipath form
New List(Of String)From{"1","2","3"}

when the form appears, it defaults to the last option (3)

how do i change this default value? i want to change it to be blank

Hi @jack.chan

Please show me the select item activity for this dropdown?

theres no select item activity, im not trying to click on a form. its a form i created.

did you give any default value here?

thanks, yes i did give default value, but doesnt seem to work if i pass in dynamic list as argument

If i hardcode the options then it will work

@jack.chan Just follow this documentation

Just change the field key and everything will fall into the place.
