Form
Provides a basic way to validate your form and show feedback to your users with native HTML5 form validation. Use attributes such as pattern to add other validation rules.
novalidate must be present on form to handle validation with javascript.
INFO
Compatible with any reactive framework, but updates will not propagate to the virtual DOM.
For advance form of validation use VeeValidate, React Hook Form or others.
