Display one topic inside another topic

Hi friends, 

I need a way to display the content from one HTM topic to another.

Let’s say I have two topics:

• Dynamic/Topic 1 – This topic has the information that might need to exist in more than one area. Its information might change, I might even change its file path, file name, etc.,
• Static/Topic 2 – This topic should display Topic 1’s content. Other than the information Topic 2 is displaying from Topic 1, this topic can never change.

I know I can do this in one of the following ways:  

• I could copy and paste topic 1’s content into Topic 2.
  • This is manual process that I’d like to avoid.
• I know I could create a Cross-Reference to link the user from Topic 2 to Topic 1.
  • I don't want to make the user have to click a second link.
• I know I could create a snippet of Topic 1’s content and add it to Topic 2.  
  • I would have to update topic 1 and the snippet each time.

Ideally, I would love to insert an element into Topic 2 that automatically pulls all the content from Topic 1. I don’t know if that’d be a div container or iframe.
