With Tooltip Slider for React

No. The bubble is a div in a relative pt-6 wrapper, absolute -top-2 with bg-primary and text-primary-foreground. It is always visible and aria-hidden, since the slider already announces its value.

Its inline start is set to the value as a percent, and -translate-x-1/2 centers it on that point. It moves on every step, while you drag or use the keys.

The value lives in state, starting at 45, and goes back to the slider as value. The bubble prints it with a % sign. onValueChange receives the new value, and the handler stores it as an array.

The bubble is placed by the raw percent, so near the ends half of it hangs past the track, and it can sit slightly off the thumb. Clamp the position if that matters in your layout.

The Progress text is a visible Label, and the slider gets the same name with aria-label, so screen readers announce what it sets. On Base UI, aria-label is one string on the slider.

0 to 100, which matches the percent used for the position. min and max set the ends.
