Dreamweaver CS3 has iFrame support
A very obscured feature I have overlooked is the support of iFrame in Dreamweaver CS3. It wasn’t even mentioned in the Help documentation. In the Layout insert toolbar, I noticed there is a new iFrame object. Somehow the Properties Inspector does not see the object. Fortunately, the Tag panel can be used to set the attributes of the object so I don’t have to resort to handcode all the time. Another point to note is that DW does not render the content in design view. I hope in future release, the object will be improved.
