I use this online form builder that WordPress supports:
Just create an account here and choose a template or customize your own. Then click here to see how to insert the shortcode in WordPress. It’s easy kapeasy! (Sorry that isn’t even a word but I like the rhyme)
Or you could also insert a form straight from WordPress like how you insert a photo.
Just click on that and customize the fields. This is easier kapeasier!
Thanks for asking! To ask me more, go here.
