open bottom up menus add/remove menuitems poorly

[aaronreed]

I have a DropDownButton? located toward the bottom of the browser viewing area and click it to popup the menu. The menu pops up, rather than down, due to the button location, as expected. However, if, while the menu is open, I add or remove menu items, the menu behaves oddly. If I add menu items, the menu does not grow up, but rather grows down and thus covers the DropDownButton?, making it unusable while the menu is showing. If I repeatedly remove the first menuitem, they disappear from the bottom of the showing menu without repositioning the menu. This makes the menu no-longer connect with the drop-down button.

That's true, there's no infrastructure for the dijit.util.popup() code to detect or handle changes to the size of the menu while it's being displayed.

We might be able to solve most of the problem by just anchoring the menu by specifying style.bottom rather than style.top.

Probably won't fix this, I don't want to complicate the popup code.

I think your workaround should be to call dijit.placeOnScreenAroundElement() to reposition the Menu after you have added items to it.
