Can't see other items in Menu

[Marlon Ng]

Hi guys.  When I open the file browser PCManFM, there is an "Applications"
on the left panel. Upon clicking it, I see the exact same things as when I
click on the Menu button on the panel bar. However, there are a few things
in "Applications" that are NOT in the Menu. These are:


Electronics
Programming
Other
Universal Access.

Can someone explain why? And how do I make them show in Menu?

Thank you for your time.
