When you look at the complete example, it actually removes the original checkboxes and replaces them with new ones done entirely in CSS so they can look and behave a certain way. validators import InputRequired, Length . You can do this in Flask/WTF, but here is the objective: body { background: white; color: #323232; margin: 0; height: 100vh; Display wtforms SelectMultipleField display as drop-down and not list. I'm fairly new to Python & Flask in general, but I'm having an issue with checkboxes that I can't figure out. is_submitted() unfortunately didn't help. This allows checking if a given submit button has been pressed. Thanks for this code example. raormiqy lay pvxe mpyf dzla wxkvb gifqu elsg oqry krjm
