How to embed my web page with iframe inside my dash dashboard?

Hi, no idea of title …

I’ve tried with this:

                                html.Iframe(width="560", height="630", src="Ranges white viewer/index.html"),

but does something wierd … it shows the left tab of the dashboard (the iframe shows the dashboard again) … don’t know why or how to make this work.

the html web is inside a folder called Ranges white viewer

do I have to use callbacks?

problem solved using static folder.
