I think you're imagining a constraint on WF2 that doesn't really
exist. WF2 can be used in chromeless windows. However, you many mean
that WF2 will primarily be used in a standard browser window, in which
case I would agree that a HTML-based menubar could cause confusion.
Then again, I've seen Java applications in a browser that have such
menubars, so there may be a demand for this. Another thing is that
someone may want to create a simulated desktop interface where they can
open multiple "windows" within the browser windows. In that case, it
would be nice if these window-like blocks could have their own menubars.
A lot of user confusion-type issues are possible here, so we should
probably discuss this at length.

Agreed. Overriding the browser's own menus should be off the table.

This is actually a bigger problem with non-chromed windows. (Unless
you were referring to the browser-menu-override situation.)

One thing we could do is come up with a way to display menubars on a
few key operating systems that doesn't confuse users, then allow enough
room in the spec for user agent vendors to create their own solutions.

I've seen quite a few sites that have horizontal navigational
buttons on the top, many with menus that drop down from those buttons.
There may actually be a significant demand for a properly stylable menubar.

Why not simply have vertical and horizontal alignment for menubars?
Personally, I wouldn't mind a better <link>, perhaps some better
styling rules and such, but most of the browser UI for <link> is
document centric. For instance, Mozilla 1.7 keeps common document
navigation buttons at the top level of the Site Navigation Bar, while
lesser used items are in submenus.
Furthermore, HTML 4.01 allows support for <link> to implemented in
any way the UA vendor chooses, so suddenly turning <link> into a menu
system could cause serious problems. This is especially true if a
browser vendor chose to put <link> items in a submenu off the main
browser menu. We're better off creating a new menu structure instead.

A bar can be vertical. I've seen many toolbars that can be
positioned that way. The Windows "Taskbar" can be vertical. I don't
really think this presents a serious conceptual problem.
As for a default direction, I'd rather have CSS or an HTML attribute

On a chromeless window, it probably SHOULD look like a native menubar.

How would they do this, by setting the |style| property equal to
"display: inline"? Keep in mind, an element name like "menubar" or
"menulist" can communicate more than just visual position. Native
menubar rendering on a chromeless window, for instance, would be
impossible without such an element.

I don't mind presenting <menu> as a button when not in the context
of a menubar. However, should this be required in the spec, or simply

You're confusing the implementation of a drop-down list for <select>
with the <select> element itself. The <select> element could be
implemented in a manner similar to that shown in the HTML 4.01
specification, for instance:
The <select> element could be implemented as a pull-down menu.
Besides, in the context of using <select> WITHIN <menu>, a pull-down
menu would almost certainly be used.

I understand that there are those who oppose submenus for good
reason. I would personally agree that submenus should be used only when
absolutely necessary. That said, I know from personal experience that
there are applications that simply cannot do without submenus.
Furthermore, I suspect that submenus will be most common in menu systems
that have a fixed position, and therefore will be far less likely to
break motor memory. Submenus are, unfortunately, a necessary evil.

Easy to fix. Display the <option> |label| as in the menu and the
child text of the <option> as the selection. This is consistent with the
example from section 17.6.1 of the HTML 4.01 spec:
<FORM action="http://somesite.com/prog/someprog" method="post">
<OPTION selected label="none" value="none">None</OPTION>
<OPTGROUP label="PortMaster 3">
<OPTION label="3.7.1" value="pm3_3.7.1">PortMaster 3 with ComOS
<OPTION label="3.7" value="pm3_3.7">PortMaster 3 with ComOS
<OPTION label="3.5" value="pm3_3.5">PortMaster 3 with ComOS
<OPTGROUP label="PortMaster 2">
<OPTION label="3.7" value="pm2_3.7">PortMaster 2 with ComOS
<OPTION label="3.5" value="pm2_3.5">PortMaster 2 with ComOS
<OPTION label="3.7R" value="IRX_3.7R">IRX with ComOS 3.7R</OPTION>
<OPTION label="3.5R" value="IRX_3.5R">IRX with ComOS 3.5R</OPTION>
Unfortunately, IE, Mozilla and Opera ignore HTML 4.01 specified
behavior regarding the |label| property of the <option> element:
