Django + Vue.js What is the best way to make a shape variation?

Question

Django

Good day.
Tell me, please, the correct/adequate/use-case version of the form validation. Input: Django model with multiple fields, reactivity via Vue.js. There are many fields that are mutually exclusive and depend on the user's previous selection, but they are required fields (in each of the selections). I hide them from the form on the front, with v-if(and the Flatpickr fields with v-show) attribute.
So, if you do validation through Django (or rather, don’t do it, but use the built-in one), then such fields will not be validated (logically), since they have blank=True. Otherwise, on the field hidden in this way, Django will swear, but the error will not be displayed - in fact the field is not in the DOM.
On the other hand, giving all the validation to the front will work, but it’s somehow scary.
I'll be glad for good advice!

Answer 1

async-validator - quite satisfied.

Answer 2

I did both types of validation myself, since my username and captcha are also checked for presence. That is, in vue I do validation on required, phone format, password match and complexity, min length. On django, that such a user is not registered, captcha, left the required check. The form is checked by ajax, I display errors from django in the same place where I display vue errors.
