I just tried for the first time setting the custom field to its HTML tag name and it worked perfectly, but what’s not great is the HTML tag has nothing to do with what the field means. It would be nice if we could separate the names to leave a helpful description primarily with the HTML tag separately and hidden behind editing.
ie. if I had a tag that you needed to name “input232” but the actual meaning was “House number”
That way it will match both… and if there is no input called HouseNumber, then just having it there will be a reminder… but it will match if they just so happen to create an HTML element named HouseNumber lol.
