[xubuntu-users] Menu editor question

[Phil]

I have the same app in several different categories, actually, I have 
several different apps repeated in several different categories. How do 
I keep an app in it's correct category and remove it from the others?

Also, is it possible to create sub categories?

I've tried to search the Internet for an answer but my connection is so 
poor that I keep losing the connection.
