[TYPO3-core] RFC: bug #6831: Refactored Clickmenu is cut off on the left, when does not fit in the viewport

[Helmut Hummel]

Hi there,

this is a SVN patch request.

Branches: Trunk only!

BT Reference: http://bugs.typo3.org/view.php?id=6831

Problem:
When having long text in the Clickmenu (like the German clickmenu of the
pagetree) and therefore does not fit in the viewport, it is cut of at
the left side, which is bad, because it gets unreadable.

Solution:
Adjust the click-menu to the leftmost positon of the viewport, so that
is cut off on the right.

Notes:
This bugreport is related to this commit:
http://typo3.svn.sourceforge.net/viewvc/typo3?view=rev&revision=2682

Look at the screenshots in the bugtracker, to see the visial effect of
this patch.

Perhaps Benni can make the code more beautiful, since I'm really no
JavaScript Guru, but the Idea should be clear.
