Menu - Blur effect

Hello!

Nearly finished with my Menu, now all I want is when I click options, for the options to be fully visible but the main menu bar and background to blur, therefore the Options stand out… Is there a way to do this? I can’t seem to do it with my method of two cameras.

I would probably find a blur shader, put it on a transparent plane and then put the plane in between the item and the background. Obviously you will bring the selected item forward towards the camera so there is space to put this plane. That would be one way to do this.
