How do i target a part of the site with a link

Okay, heres my problem. I have a button that loads an external text file into a dynamic text box. This text needs to consist of many different links. I have this completed. However, i need the links to open somewhere on the same page, not in a new window.

2 things that make this more complicated :scream: :

  1. The links need to display a text file or a paragraph somehow, not a website.
  2. Ideally, i need the link from the dynamic text box to target two separate places at the same time. (an area with a picture of the product and another area with a description of the product)

Can someone please tell me how to go about doing this?
