[GeoNode-users] Customize structure of metadata in geonode 2.4

[admire]

Hi

I have geonode 2.4 installed via docker and inside the metadata document 
I see it is generating url with localhost for the even though I changed 
PUBLIC_LOCATION to point to an external ip. How can I ensure that 
localhost does not appear in metadata.

I also need to customize the section for supplementary information in my 
metadata so that my app can use it. I have changed full_metadata.xml to

     <gmd:supplementalInformation>
          {{ layer.supplemental_information }}
        </gmd:supplementalInformation>

But with this change I cannot update my metadata document as it throws 
an error.

Error updating metadata. Please check the following fields:

  *
      o Category is required.

It seems to disable the Category tab.

Regards
