How do we add the tags?

In item page - right column - "update tags"

I don't have that.
Just tried logging out and back in, but I don't have that in the right-hand menu.

ops! I have to check if it's possible from Workshop interface for owners.
It looks like Workshop doesn't allow to update tags after publishing - weird :(

But the most tags will bee needed in lanscape, with over a thousand maps in which it is difficult to find the right one.
e.g.
- flat
- hilly
- mountainous

- with infrastructure
- with cities
- with mods
- populated

- with sea
- with river
- Island

First I need to tag existing vehicles and buildings - later we add tags for maps.
In the future version of the game, modders will be able to add w new tags for items.
Surprisingly, the Workshop doesn't allow to add tags by authors after publishing. Only moderators can do it.
