Proper way to insert an iframe in WD Pro 17

I can't find anything in the help specific to how to insert iframe code into a web page. Any pointers? In this case it's a simple insurance calculator that is 400x400 pixels approximately. (I know how to code for iframe, I just don't know how to insert it into a page. Thanks in advance! Mike

Draw a rectangle (in theory, any shape). Then click Web Properties > Placeholder (tab) > HTML body (code) and add your iframe code there.
