**For each blog-post** on my wordpress-blog I'd like to have Teaxtarea where i can pass **additional content** for that post. 

In my case that would be an unordered list which contains a quick overview of the content. 

That additional content should be displayed in the **preview of the post on the blog-preview-page**.

My problem:

I am actually not sure on how to best add this additional content and then pass it to the preview.

**Do I use wordpress' custom fields for something like this?**

I'm gratefull for a push in the right direction.

Thank you,
Nils
