Issue #1: Basic toolbar example - when hovering over other items after clicking on 1 button the expand of the menu is 1 behind where the mouse is.
Issue #2: The expanded menu list isn't aligned correctly the first time to a 't-b?' menuAlign/defaultAlign. Using a custom Ext.menu.Menu which allows hbox and vbox layouts. Only custom css used was to place a custom image instead of text but can recreate it using text only.
Issue #3: when setting an element width in the config of a menu item it is overwritten to the default minWidth set in Ext.menu.Menu.
Issue #3 is cause I have no text set and was using css images to set the width and height so the minWidth got set even if the config had a width or not.
I'm going through this in more detail right now and will update this thread with the results.
Let me wrap up some test code for you. I've been going through the code.
I customized the Ext.menu.Menu source to handle vertical: false kinda like the toolbars does.
I've been talking with Mitchell Simoens a few about this on my other forum user account.
So if you want more details just email me.
