Water fountains can have bottle fillers too

[endolith]

The quest for water fountains gives multiple options, but doesn't allow to combine them. It should behave more like a checkbox than a radio button, allowing you to say that a fountain has both a bottle filler and a drinking fountain, for instance.

You seem to have missed the word "only" in "Refilling bottles only" answer. So if there are other ways to consume water from that amenity, than that one is not the correct answer, and you should choose another answer which best describes the amenity.

Because, you can fill bottles also at "water fountain emitting small jet of water", "water tap", "hand pump", "other water fountain" etc....

And yeah, there will always be special cases which are similar, but not exactly as one in the pictures... Just choose the one which matches the amenity the most. If still unsure, choose "Other water fountain" which is supposed to cover all special cases which are not one of the other displayed answers.

So, if I'm interpreting your picture correctly, it is "Water fountain emitting small jet of water".

Why can't StreetComplete invent new tags?

see https://wiki.openstreetmap.org/wiki/Any_tags_you_like#When_to_create_a_proposal especially from Your feature is of general interest and below. Also, it is a good policy IMHO. Note that StreetComplete has a lot of users - any tag it might invent would be massively used, and if not accepted by community, would cause massive amount of complaints. Even quite accepted and documented features like feature=no have repeatedly drawn enough negative attention that a FAQ entry had to be written explaining the SC position.

As for the multichoice - it is a bad choice (no pun intended!) if not all pictures can be combined in all ways (as they can't). Also, semicolon tagging is often not supported by data consumers (speaking of data consumers; where/how do you envision collected data proposed here to be used? Do you already have some app which is able to use it?)
If only some combinations should be accepted, then multi-choice should not be used, but instead single-choice should be used, and combo-answers should have their own pictures. But then one sacrifices simplicity and provoke bad tagging (e.g. users might likely click on first picture that looks correct, even if there are other pictures which describe situation on the ground more precisely).

I personally would probably mark unknown combinations as other water fountain (which it is), and not worry about details. Or if I felt very strongly about usefulness, I'd select other answers / leave a note and then mapped it as specifically as I wanted when I got home (or even open Vespucci/Everydoor on the go and edited directly there). Yet I guess I would feel strongly enough only very rarely with this particular quest (if ever). But that is just me, YMMV.

Why can't StreetComplete invent new tags?

It is more of self-limitation done for practical and political reasons.

There can be still new tags invented as during StreetComplete development it was discovered that they are needed, but discussing them should not take place on SC issue tracker. But rather in place where wider OSM community is present (community.openstreetmap.org or tagging mailing list for example).

But yes, I don't know the best way to tag other combinations, like a bubbler and a dog bowl fountain.

Could we have a quest if amenity=drinking_water has a dog bowl?

This quest has me confused too, but for a different reason. Most of the drinking water sources I like to tag are rural/mountain area sources that are often springs, but don't look like any of the pictures of the quest. They typically look like this

They're called "cesme" and similar words in South_eastern Europe and the Middle East. Which option should I choose for answering this quest?

The wiki ( https://wiki.openstreetmap.org/wiki/Tag:amenity%3Ddrinking_water ) says:

natural=spring indicates water flowing naturally out of the ground. It may have an amenity=fountain built around it, for example see Roman Bath in Bath, U.K.

Which seems to answer the how to tag it bit.

Which option should I choose for answering this quest?

So I'd guess from that and the code picking spring would be appropriate.

I think where it gets challenging is that as an outsider I wouldn't be able to tell whether that was fed from a spring or a water pipe (aside from the lack of presence of a tap. I don't know how you'd survey that bit unless it was signed?

[rhhsm]

Maybe the image for "spring" could be replaced by one which shows water in a more easily drinkable form (I find it hard to imagine how to drink water from the spring shown in the image, and wouldn't think of it primarily as a source of drinking water). The image I was tempted to choose is "other water fountain".
What tags are added to the node when choosing each of the options?

You could fill a bottle from it for example. I think it's more in the traditional map sense of the spring is the source of the water and would be marked on a map (compared to part way down a mountain stream where you could also fill a bottle).

The image I was tempted to choose is "other water fountain".

As I say, I don't think that would be unfair given what you're seeing.

You can see the tagging here:

You can see also them in undo menu. You can enable airplane mode for the entire phone (or manual upload mode in sc) and experiment with answers and undo test edits - and while undoing edits you can see tags applied, even with links to wiki.
