How to save dynamic data into a text box

[etcsocial]

I would like to create a textbox in my app that allows the user to see their previous entries. The idea is to see the entries that they enter previously while they enter a new entry.

You can do this in the initial content area of your text box editor (I put in the website URL in the screenshot below). Enter whatever dynamic data you want in there. Is this what you mean?
