Enable HTML in items/show

How can I enable HTML formatting for some or all fields to appear on the public pages? I've found out how to enable it for SimplePages but not for regular item pages.

For instance, I added some bold formatting and hyperlinks to the TableOfContents field for an item. I can add and view HTML formatting on the admin view. The HTML, though, is stripped on the public view: https://wbexhibit.otis.edu/items/show/18.

We're using the Santa Fe theme. I'd only want to enable HTML formatting for DC.Description.* fields. Please advise.

We are also using the Santa Fe theme and are having the same problem. I tried switching the theme, to Thanks Roy, and it did not work either. We had a short list in the Description that was formated using

    but it doesn't show.
