How can I disable scrolling in Web AppBuilder?

[NatashaKypfer]

I am using Web AppBuilder to build a Web Mapping Application that I am trying to embed into a WordPress website.

I am currently trying to embed the map into the site with an iframe, but as one scrolls down the page, once they reach the web map, they start zooming out on the map instead of scrolling down the page. 

I have tried modifying the CSS of the iframe with "overflow: hidden" but this will not work. I have tried looking around for other solutions, but to no avail.

Can anybody offer any suggestions? I would figure this is a fairly common issue for anybody embedding a map into a website. 

Thanks

 Im also encountering this as a major problem. I have built a series of maps using ArcGIS Instant Apps that do not work well when embedded on a website. The maps prevent the user from scrolling down on the website because once they scroll over the map they start automatically zooming into the map. How can we disable this scroll function?
