Choose a concept from a hierarchical vocabulary
We do have some vocabularies, that do have a hierarchy, e.g.
discipline. When adding a concept from such a hierarchy it shows up in the edit forms as a flat list. But for quality of input it would be good to see the hierarchy, otherwise it is only a good guess to find the best concept. If the hierarchy of the vocabulary could be shown in the drop-down-list, it would be easier to either drill down to a narrow concept or use the broader one.
In backend the hierarchy is implemented (have a look at
/api/vocabularies/discipline) through the relations
broader - it could be visualised like in the Skosmos view of https://vocabs.dariah.eu/oefos/en/ when clicking on
