Component: Slider about calcite-design-system HOT 8 CLOSED

Hey, we didn't have plans to change the design of this for 2.0.

Ideally the functionality we'd add in a web component would be things like support for multiple handles, scale options, better data ticks, value display etc. It'll also be easier to style since browser support for range inputs is pretty inconsistent 🙏.

I think we need to modify the above designs to have both handles vertically centered on the range track, especially in dense applications.

The above labels also interfered with form labels and can take up a lot of vertical space, if I remember, so we'll probably want to adapt for that, and keep in mind use cases where the input fields are not necessarily attached to the handle, like in @patrickarlt screenshot above.

For potential future reference this is the zoom slider we are using in the vector tile style editor.

Would love to replace this with something from this repo.

Following Adam's comment:

The initial (basic) slider is already in 1.x.
https://esri.github.io/calcite-web/documentation/components/#sliders

For 1.x we had the basic slider, but there are more features we want to add, like notches, range, etc.

Here's a mock-up:

Though the concept of the low-end range handle is nice (below the slider), it proved faulty on mobile when sliding as the value is hidden by the finger. Therefore, it's best to keep the low-end range value displayed above the slider.

I am 100% ok with changing the design in VTSE to have the inputs attached to the handles as per the designs in #4 (comment). Not a firm requirement on our end.

For sure, IMO it adds unnecessary y-height because you also need to accommodate for a label above the handle, and most use cases for multi-handle sliders will likely be in more data rich / dense UI.

Maybe a prop option could allow for both options!

I have been thinking about scaling for things like this... I could see a "half" scale modifier being useful for VTSE or other really tight interfaces. Same for dropdown, etc. Could set a "scale prop" modifier on a per component basis for type and padding scale?

On the off-chance somebody wants to pick this up while I'm out next week my in-progress work is staged on the paulcpederson/loader branch.

Any further work to the slider can be opened as new issues. Closing for now.
