Tree: show values of specified properties next to the labels

[aleksejrs]

Codes in classifications of products, services and economic activities are hierarchical, e.g.

• 1 → 11 → 111 → 1111

• 1 → 12 → 121 → 1211

It would be helpful to see the codes (values of chosen authority control properties) in the tree.

https://tools.wmflabs.org/wikidata-todo/tree.html?q=540912&rp=279&sp=12345,12346 (not actual property numbers) could then show something like (assuming there is no table):

• Oil and fat industry (OKVED 1.1: 15.4, OKVED 2: 10.4)
• Производство рафинированных масел и жиров по ОКВЭД 1.1. (OKVED 1.1: 15.42)
• Производство растительных рафинированных масел и жиров по ОКВЭД 1.1. (OKVED 1.1: 15.42.1)

or

• Oil and fat industry (15.4@OKVED 1.1, 10.4@OKVED 2)
• Производство рафинированных масел и жиров по ОКВЭД 1.1. (15.42@OKVED 1.1)
