I came across this problem too.
What I did was first give the dropdown an id in the form settings.
Then I used jQuery to look for the — and replace it with the text string you want.
—
$(“#howdid option:first:contains(‘—‘)”).html(‘How Did You Hear About Us?’);
—
in this example the id is “howdid”
the jquery looks for this id and then finds the first option. it checks that its value is — and then swaps it for “How Did You Hear About Us?”
This is my first reply so hopefully will help someone.
