Introduction

RequiredMixin is a mixin that provides basic properties for elements on the page that can be required to have a value.

About Mixins

Mixins provide functionality that other elements can inherit and use.

Mixins are not elements. You cannot add mixins to a page in the Editor like other $w elements, and mixins are not meant to be used directly in your code.

For example, you would not write code like this, because it is out of context:

$w("#RequiredMixin").required = true;

Instead, you can code the following if myElement is an element that "mixes in" RequiredMixin.

$w("#myElement").required = true;
