The default KDE menu type in Linux Mint 17 is application based.
This is similar to Ubuntu unity dashboard where one can search for apps and files and access them.
However, if this needs to be changed to the more classic style which has only the groups > programs format, that too can be done.
Here is how :
Right click on the KDE menu icon and choose “Switch to Classic Menu Style”.
Access the menu after this change, it will be very classic and simple to access.
