[SOLVED] Related items filter and category filter do not combine as expected

hi, all,
In backend, I have a related field. When I select a category the item select not filter items, but it shows all of them.
FC 3.1.0-rc2
Joomla 3.5.1

Hello

yes it was never supported, and the description also says it,
Only fields:

select / selectmultiple
radio / radioimage
checkbox / checkboximage

are supported in backend
we have already made change for this in upcoming to only all selecting the above fields as backend filters

so if you are talking of backend items manager then yes it is not supported, and new version makes this clearer

Wow,
Then If i want to filter items by category in a related field in my backend, i have to create my own code, no?
The problem is that I have many item with the same name in several categories (client mandatory), and it's difficult know which is which.

Sorry for insisting, but before I believe the item could be filtered by category. To ensure attach a screenshot of the two related fields.
Sorry again.

Hello
