One of the pleasant problems with Linux Distros is the huge number of applications available. For Ubuntu Ultimate Edition (and others) there can be so many applications in a Kmenu section that it covers the entire desktop like this:

So, how to fix this? You want to make the Kmenu more organized using submenus. Just highlight an item in the section of Kmenu you want to change and right click. A menu will appear, just highlight the "Edit Item" option and left click. This will invoke the KDE Menu Editor:

Now use the Menu Editor to add a new submenu. Just click on the "New Submenu" icon, give the new submenu a name (Web Browsers in this example) and then drag the submenu to where you want it in the main menu:

Drag items from the main menu to your subfolder and arrange them as you see fit. Keep adding subfolders and moving items until it's all the way you want it:

The default icon for a submenu is a frumpy yellow box. Why not a nice folder icon instead?

Drag items from the main menu to your subfolder and arrange them as you see fit. Keep adding subfolders and moving items until it's all the way you want it:

Once you've added submenus and moved the items, Kmenu will look much nicer and take up a lot less space on your desktop!

Nice to have your desktop back, isn't it?
