Feature request: tooltips on input fields

[dnmeid]

When offering the user an input field like textinput or dropdown menu it should be possible to to show a tooltip when hovering over the input. So we can offer some additional information about the expected input data, like its format or what it is good for.

I think we should add "placeholder" support too. For showing example-data inside text fields.

shouldnt the placeholder be the default value instead?

[haakonnessjoen]

A placeholder gives an example of a value. But often not what you want. A default value is most likely what you want.

[dnmeid]

Ok, but how should be placeholder and default value implemented at the same time?
I think it is easier to go with the default value in the field and you can additionally show examples in the tooltip.

When you specify just placeholder, the tag has if you have defined a default value, the tag will have

Placeholders are spooky, we might want to have no value in the field.

[haakonnessjoen]

Placeholders are exactly that, no value. But tooltips could be ok to. But maybe they should be some magic kind, that appears without waiting long for it.

I know, that is the problem. If the placeholder says "hello", and I want the field to be EMPTY instead of "hello", that won't work with the placeholder-approach. Rather a default value with a tooltip.
