Embedding iframe in item fields

Hi all,

I’ve been looking at the various threads for embedding iframes into simple pages or exhibits, and I can get it to work on pages, but I was wondering if it’s possible to embed iframes for items?

Basically my items are people, and I want to embed a timeline of events in each of their lives to each person’s item page/entry (in a custom ‘timeline’ field, for example). I’ve tried using the HTML editor and I’ve added iframe to the list of HTML elements (as I say, it’s working in simple pages). When I put the code in, it renders fine in the editor, but when I save and go to the page it doesn’t work. Would there be any way to make iframes display in item fields?
