hi,

Just curious why:
1. the overlay HTML structure class name are changed from "bd" to "yui-widget-bd"? is it for backward compatibility so old YUI2 module and YUI3 overlay could co-exist?

2. In YUI3, there is no longer a Module component. I have just encountered a case that I wish to make a module that use a "flow layout", i.e. doesn't position absolutely nor align to any other element. is there a plan to support this use case? or is there a chance to make an overlay to use flow position but not absolute position?

Hey mingfai,

"bd" was too generic. It would conflict with both rules for non YUI "bd" elements, as well as "bd" elements defined by other components. That's what prompted to "yui" and "widget" prefix. Other specialized components could replace "widget" with their particular component name (e.g. yui-datatable-bd)

As Eric mentions, you can build one using a custom mix of extensions, so you're not bound to all the features of any one class. e.g.:

http://developer.yahoo.com/yui/3/exampl ... build.html

We will probably end up packaging a statically (or relatively) positioned "Module" out of the box - but it would effectively be the same as the class built from a custom mix of extensions above.
