I have tried setting the disabled flag to the entire slider, but the thumb will still have the halo effect when clicked.
.MuiSlider-thumb.Mui-focusVisible, .MuiSlider-thumb:hover {
box-shadow:none !important;
}
However, it would be nice if you provide a working example next time so we don't have to dig into documentation just to help you. Ty.
