Sometimes we use placeholders as form labels instead of separate form labels for each field on CF7. That’s okay because there is an option on CF7 field settings to do that.
But using the first option on a DropDown field as a placeholder is a bit tricky.
Please use the below method to use the first dropdown option as Placeholder which would have BLANK Value.
We have to use first_as_label option like below.
[select name first_as_label "Select Names" "Amit" "Ram" "Shyam" "Tom"]
