* renames RoomTooltip to be a generic Tooltip (which it is)
* hooks it into Field to show validation results
* adds onValidate to Field to let Field instances call an arbitrary validation function
Rebased from @ara4n's https://github.com/matrix-org/matrix-react-sdk/pull/2550
by @jryans. Subsequent commits revise and adapt this work.
This allows Fields to have an optional prefix component which is placed inside
the border of the Field and to the left of the input. Since this label animation
would be complex to get right for this case, it is instead fixed to the top left
if there is a prefix component.
This canonical example of this today would be a phone number field which
includes a country dropdown.
Several small tweaks to the props handling:
* Use destructuring instead of `delete`
* Emphasize the `element` as a primary prop
* Document `textarea` as supported
Fixes https://github.com/vector-im/riot-web/issues/8250
This keeps all fields in line with the design without them having to defining it twice. The option is kept in the first place as some fields might want to override the placeholder to be longer than the label or something.
The label moves into the border on focus and after being filled. A valid color
is applied to the label and input border. Other states like invalid can be added
later as needed.
Adapted from @ara4n's experiment into a React component with a CSS only
approach.
