<input type="range" min="1" max="3" step="1"> draws as an unmarked slider that slides smoothly from one end to the other. It would be nicer to have tickmarks and to snap to them. Try using Opera for a sample experience.

Hixie says: Draw tickmarks as given in list="". If no list="", draw them for step="", unless step has been set to "any". Hyatt says:

Bah, didn't mean to submit that yet. Anyway, Hyatt says: Don't want ticks by default. Perhaps also no ticks for step=1.

My proposal: Do what Hixie says, but also don't draw tickmarks if we don't have enough room. Assuming 1-px ticks, you'd need 2n + 1 pixels or more. If the theme only goes down to k-px ticks, we'd probably want k(2n + 1) free pixels; below that, no tickmarks + no snapping. Hopefully, this avoids breaking too many existing Mac widgets that don't want tickmarks, e.g. the Safari RSS widget, because they'd fail the 2n + 1 test.

Is this issue still valid? If yes, I would like to propose a patch for the same.

This was done as <datalist> support.
