how to pass the form to HTLM page using Flask

@app.route
form = CountrySelectField()
return render_template('up_profile.html', form=form)

the webpage.html

<div class="form-group">
  <fieldset>
    {{ form.self.choice.label(class="form-control-label") }}
    {{ form.self.choice(class="form-control form-control-lg") }}
  </fieldset>
</div>

if I use self.choice or only choice the error es same in the:
jinja2.exceptions.UndefinedError: 'wtforms.fields.core.UnboundField object' has no attribute 'self' or inja2.exceptions.UndefinedError: 'wtforms.fields.core.UnboundField object' has no attribute 'choice'

@dhernandezgt My snippet is a Field not a Form, you can find more info on Fields and Forms here https://wtforms.readthedocs.io/en/2.3.x/crash_course/

I created a package for this using your gist and also a StateSelectField that uses a similar approach.
