The Launchable HTML feature, which is available under Settings on YUDU Publisher, is a nifty little feature that lets you add an extra button on your digital edition's toolbar menu in order to trigger a piece of custom html content. This allows you to access that content no matter where you are within the publication.
It could be used for a static help page, an explainer video or an interactive form - literally anything that can be created in html.

Depending on the content, you may wish to customise the icon that is used for the Launchable HTML. This can be done by updating the relevant image assets in the "artwork" folder in the HTML Reader Branding Pack. For assistance updating the Branding Pack, please ask a member of the support team.
