how i can Add eg. a dropDownBox(List) additional in the "Edit Metadata Form"? I know it is possible when i modify the part of "share-form-config", but how i make it? sry for my english .
It is for an aspect, even if you don't want to add an aspect I am sure it will still help you, because you won't have to create a new context and a model, you just have to add you new field in share-config-custom.xml and decide when u want it to be displayed, either on Document Library pop-up Edit Metadata form, Document Library Inline Edit form , etc.
