Adding an Action to Jenkins without displaying it on the left menu

[MaxiTrompe]

Hello, 
 
I am trying to create actions in Jenkins without having them to appear on 
the left side of Jenkins main page.
 
For this, I have created a list of Actions, that work fine, but they always 
appear on the left side.
 
I don't want these actions to appear because I just want to create a page 
in Jenkins which has these action's url.
 
If anybody knows how to do this, it would be great
If some specifications need to be defined, please ask
 
Thank you
