Guild Wars 2

when i open trading post i can sell any item except the staff or weapons it don’t appear one the sell-able list and i cant even post it by using the right mouse button

There are several possibilities:

1. The items are in an “invisible” bag (nothing can be sold from those). Move it to another spot in your inventory and try again.
2. The items are account- or soul-bound and cannot be sold at all. (You probably checked that already, but just in case.)
3. Something we cannot spot easily: try moving the items to another toon and try from there.

If it’s none of those, I recommend creating a support ticket so you can get individual attention on the matter.
