To open any link in an iframe lightbox, simply add the code below to the anchor tag.
rel="shadowbox;"
You can also add an ideal height and width as follows:
rel="shadowbox;width=860;height=485"

rel="shadowbox;width=860;height=485">a link
When editing a text module, use the HTML preview button (marked with HTML on the button) to edit the html directly.
