How to render HTML in a textbox?

[AAOM Tim]

I would like to take some HTML content and render it in a textbox with the
HTML formatting applied to the text, but when I assign text with tags they
are HTML-encoded. How can I display it as formatting text insetad of showing
the HTML tags?

The standard HTML textbox cannot display formatted HTML.
An alternative would be to use something that looks a lot like a textbox but
has enhanced functionality.
Here are some free options:
