cssClasses - how to use, and is it even supported?

[smileBeda]

Here it is said that cssClasses is an option but the option doc does not mention it, and no matter what I pass to the option, it always ends in undefined classes produced in the HTML.

I then found

noUiSlider/src/nouislider.ts

Line 4 in faa3252

target: string;

and if I pass all of those classes like :

cssClasses: {
    target: " string",
    base: " string",
    origin: " string",
    handle: " string",
    handleLower: " string",
    handleUpper: " string",
    touchArea: " string",
    horizontal: " string",
    vertical: " string",
    background: " string",
    connect: " string",
    connects: " string",
    ltr: " string",
    rtl: " string",
    textDirectionLtr: " string",
    textDirectionRtl: " string",
    draggable: " string",
    drag: " string",
    tap: " string",
    active: " string",
    tooltip: " string",
    pips: " string",
    pipsHorizontal: " string",
    pipsVertical: " string",
    marker: " string",
    markerHorizontal: " string",
    markerVertical: " string",
    markerNormal: " string",
    markerLarge: " string",
    markerSub: " string",
    value: " string",
    valueHorizontal: " string",
    valueVertical: " string",
    valueNormal: " string",
    valueLarge: " string",
    valueSub: " string",
}

well... it produces HTML elements with noUi- string, which makes absolutely no sense to me. it seems to replace the class rather than append, and only works if we overwrite them all?
Indeed, I can then also overwrite that with cssPrefix: '', but... that fully defies the purpose of this, IMO.

The final goal is to add classes from Bootstrap - and that just becomes impossible, if we have to either remove the noUi prefix just to add something like a bg-danger (thus totally breaking noUI) or append to it, therefore breaking Bootstrap.

Is there any solution to this?

Correct, that is what this option does. This option is for projects that combine and style multiple UI elements into a library. I would not recommend using it in a one-off project.
