Dynamically change output component in callback

What I am trying to do is I am generating output components (html div children as dcc.loading(Iframe)) dynamically based on values user has entered in a dropdown. Now, I am having another function which generates output to display in all the respective children generated. I am not able to update the Output component in the real time. Any idea on how to do this?

Sorry I couldn’t understand your problem…
If you can share some code or MWE maybe I can help you out.
