@nishandevkar It seems there is a merge conflict there.

Which one we are planning to keep

1. validate_choice=False: then we can us the following word = SelectField('word', choices=[('', 'Select a Word')], validate_choice=False)

2. validators=[DataRequired()] then we can use

word = SelectField('word', choices=[('', 'Select a Word')], validators=[DataRequired()])

or if we planning to keep both options then we can try the following.

word = SelectField('word', choices=[('', 'Select a Word')], validate_choice=False, validators=[DataRequired()])
