About Mixins

Mixins provide functionality that other elements can inherit and use.

Mixins are not elements. You cannot add mixins to 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:

let isHidden = $w("#MobileHiddenMixin").hidden;

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

let isHidden = $w("#myElement").hidden;
