I need to set up an advanced search widget in one node of the backoffice in which I set up several values for one field. I've followed the instructions on this document:
So the conditions specified in my class which extends from AbstractInitAdvancedSearchAdapter are working and the result are displayed correctly when I access to the backoffice node. The problem is that I want to be able to see and modify those advanced search fields. I have the possibility to add new fields, but I can't see the way to modify the ones specified by code. Any advice here?
