Dropdown menu animation alternative?

[antitoxic]

The dropdown menu animation (https://www.polymer-project.org/components/paper-elements/demo.html#paper-dropdown-menu) has some quirky things involved.

1. It starts from top left expanding to lower right, which leaves the initial value unanimated (no fading or zooming out) and visible for too long. Because of this it seems that user gets the feeling that the initial value is still there, in the back and wont be changed after picking a new one from the list.
2. Animation speed is a tiny bit too slow. I can't really explain this. However it doesnt feel quite right.
3. There's another issue for animation flashing Animation flashes on second open #6

It is this by design? I mean other than the flashing? It seems weird.

I've done some research on Material Design implementations and there's quite decent dropdown here:

Could it be ported?

Bump. I agree the animation speed is too slow. I viewed the source on your link, and that is more what I was expecting.

That alternative dropdown menu is awesome. I agree this polymer version should be updated.

@morethanreal A few people have mentioned this (also over at Polymer/polymer#1146). I know you guys are swamped with 0.8 stuff, but if you get a chance to look at this, I think it would be popular.

I am finding that the animation causes text wrapping in my menus, until the animation completes. Are you guys seeing this at all?

Any update on that one? The transition still seems to go from top left to bottom right. Is this by purpose? Any easy way to change this?
