Include one app in another?

Hi,

is it possible to include one app in another app?

The problem is:

I want to display details of an entity (with dynamic display of its attributes) in different kind of ways.

One time standalone.

One time in an approval task.

One time in an approval task displayed after selected in a list.

One time in an approval process.

And maybe some other scenarios....

So in the end I don't want to build (and maintain!) my dynamic app multiple times!

Is there any example or solution for something like this?

Thanks and kind regards,

Dominik
