enter image description herei have found myslef the solution. The Symfony doc is not really helpfull when creating a dynamic customised choice menu (drop down list). I had to use the $options and to dig dip to find the solution. I am happy because the choices are dynamic and they are linked to the Library that is selected when connecting to the site.enter image description here
