Notice some issues with the bar menus...

If you populate a drop-down menu (Menubar -> BarPopupButton -> More BarButton's than can fit on screen) with more menu items than it can fit on the screen, it causes the menu to instantly close after popup, becoming unusable.

Alternatively, if the setup is Menubar -> BarPopupButton -> BarPopupButton -> too large BarButton list, then instead the menu just extends beyond the bound of the screen.

Ideally if the menu is too large, it should add up and down buttons at the top and bottom of the menu to allow navigation (either mouse-over or click-and hold). An option to specify the maximum size of the menu before this happens might also be useful.

Just a followup to the above - if the first scenario above occurs in the designer, it causes the entire BarPopupButtonLink menu to be deleted/removed after popup and this is rather frustrating to say the least.

I am now using Vista Home Premium on a notebook with a 1280 x 800 screen where this can happen all too easily (since the VS designer results in the BarManager having even less vertical space with which to show commandlinks than normal.

Any official response on this?

Hi Chien,

My apologies... it appears that we never got the notification email about your original post. Perhaps our spam filter caught it. I'll get this written down to look into soon and will follow up.

Hi Chien,

The upcoming maintenance release has some updates on this.

First, we enhanced the popup menu positioning code so that if a large popup will cover its anchor item, it will attempt to slide the menu over so that it doesn't cover it up. This should prevent the instant close issue that you had.

Second, if the menu items will not fit in the menu, overflow scroll buttons will appear. You can hover or click on them to scroll the menu up and down.
