Here is a plunker demonstrating the following issues.

• The grid menu is pretty much unusable if you are showing a grid with a small height. While I don't see too much practical use for it, if you were showing no data or zero rows, the height of the menu is 0.

This is caused by this code which was added as part of this pr to fix issue #4361

I think there needs to be a better solution to #4361 like possibly appending the menu to the body at an absolute position.

• The column menus do not behave like the grid menu.

The logic added as part of the PR above, was only done for the grid menu. This leaves a different behavior between the grid menu and the column menu. This leaves the same issue described in #4361 for the column menu as shown here on this plunker.

I am happy to take a stab at fixing this, but wanted to get some opinions on possible fixes.
