I may be doing this wrong but:
In one of my content types, I want people to be able to select an existing node, so I can use some of the data from the existing node of content type "page".
I've installed Entity Reference. This works great but for the fact that I can only choose to show in a dropdown every page node, which in this case means a dropdown with nearly a thousand options, when really I want people to choose from a more limited section of options (e.g. where field1 = foo and field2 = bar etc). Especially as you can only see the Title of the node, which in some cases is repeated in irrelevant nodes.
I've looked at Entity Reference View Widget, which allows you to create a View, but the output isn't ideal (e.g. it's not a dropdown, but lists every filtered option with a checkbox, whereas I definitely want people to only choose one option).
Is there another module/better way/hook etc, which would allow me to filter further the Entities in the dropdown, more than just by Content Type?
