Attribute editing: value relation widget (order value)

Checklist

• [x] I've searched through the current issues to make sure this feature hasn't been requested already.

Motivation

Manage options:

• values order in the in the drop-down menu

Now in G3W-SUITE, the values show in the dropdown menù follows the alphabetic order of the value column

IN QGIS, instead, the default order is based on the key value (ever alphabetic)

There is a option that permits to order the value on the base of the values colum (ever alphabetic)

Example in QGIS

Suggested solution

It is therefore necessary to arrange things like this:

• the option is active: the values ​​are sorted alphabetically based on the value column (current behavior of G3W-SUITE)
• the option is not active: the values ​​are sorted alphabetically based on the key column
