Introduction

Important:

• This API is only relevant for custom widgets in Branded Apps.
• Custom widgets are not yet available to all users.
• This API is in Developer Preview and is subject to change.

The MobileHiddenCollapsedMixin mixin provides properties and functions that elements can inherit and use.

Note: 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.
