It seems Chromium does not yet implement support for this yet:
See: http://www.chromium.org/developers/web-platform-status/forms
Not available yet
- Localization of
- Dedicated UIs for color, date, datetime, datetime-local, month, time,
and week types
- Automatic switching to vertical range
- Value sanitization algorithms
- datalist element, list attribute, and list/selectedOption properties
Edit: Vuurwerk indicated that it is actually possible to alter the presentation using the -webkit-appearance: slider-vertical
property. Although this does transform it into a vertical slider, I would not recommend doing this, since it will break your layout and doesn't look really pretty: example.
If you really want a vertical slider, use a JavaScript solution. Support for <input type="range" />
is very basic at the moment anyway, so you are probably better off with a graceful degradation or progressive enhancement approach.
