@rvsia can you add just a regular slider for PF4? So we have something in place until there is an existing component?

[Hyperkid123]

I also see "1" character when previewing the PF3 slide:

Can you check where is it coming from?

[Hyperkid123]

It seems that the value is popping out (probably has some z-index value)

[rvsia]

@Hyperkid123 Yeah, the styling of the PF3 slider is wrong, but I did my best and copied all sliders CSS to our mastermind CSS file. It helped a lot, but it's not perfect. :-/

Yeah, I can add a placeholder to PF4.

[Hyperkid123]

@rvsia can you override it so it does not mess up the docs?

[rvsia]

@Hyperkid123

1. added a PF4 slider

2. the number in PF3 is hidden

[Hyperkid123]

The nasty PF3 ghosts are gone

[Hyperkid123]

Can we add links to the corresponding API of the MUI component? The rest of the MUI components does have this link.

[rvsia]

done
