<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Recent versions of GRUB2 introduce submenus which allow for nesting levels to appear (instead of the flat list in the past).
This patch consists of two parts: the parsing part in KDM (bootman.c) and creating a menu structure from the parsed list in ksmserver (shutdowndlg.*)
The parsing part produces a list like this:
Gentoo GNU/Linux
Advanced options for Gentoo GNU/Linux
Advanced options for Gentoo GNU/Linux>Gentoo GNU/Linux, with Linux 3.4.4
Advanced options for Gentoo GNU/Linux>Gentoo GNU/Linux, with Linux 3.4.4 (recovery mode)
Windows 7 (loader) (on /dev/sda2)
???? ?????????
which is then converted into the menu structure. These full identifiers can be properly used with `grub2-reboot`.

Also check the related bug.
The parsing part of the patch can be applied in the KDE/4.9 and master branches as well (tested and working in KDE 4.8.95 and 4.9.x). ksmserver has migrated to QML since then however, and the menu structure has to wait. Currently it looks like this: http://i50.tinypic.com/96bw35.png

Update: There is a proper fix now for KDE/4.9 and master: https://git.reviewboard.kde.org/r/105568/</pre>

Also works with a custom menu file I made (as shown in the second screenshot).</pre>
