Two Way Slider

[kishaningithub]

It would be nice if this was a two way slider i.e. a range that the user can move the Min and Max Pin and it has two outputs and not just one.

Use Case:
-> Filter by "Price Range" in a shopping cart.

Some implementations

I would be nice if polymer had this in its paper element set

Not in the specs so unlikely to be supported until then:
https://www.google.com/design/spec/components/sliders.html

It would also be useful for medical imaging, along with vertical sliders.

Few months ago I played a bit with it:

But was waiting for the range slider to get more mature before going further...

As @nicolasgarnier pointed out, it's unlikely that paper-slider will support a two way slider as it's not in the spec. Also, good to know that there's a <paper-rangeslider>. It just needs to correct the progress bar as it seems to be off a few pixels.

as it's not in the spec

So to me, a range slider is a very common and useful UI component / pattern that plenty of apps use. Are we taking the approach that just because the spec does not explicitly define a component (or in this case a permutation of a component) we do not want to support/make it?

@samccone paper-* elements are specifically for material design elements. We could have an iron-range-slider for example.

word :) sounds fair to me

[blasten]

:) that'd be a good primitive to have.

Wouldn't having it be an iron element make it more difficult since you couldn't leverage any of the paper features? Say you wanted a shadow or ripple, for example. I was thinking you could have another class of elements (that requires the paper elements) that would be for common material design based components that aren't part of the spec.

A quick update on this request. After talking to folks, material design may support range sliders in the upcoming months, so I'm reopening this feature request.

awesome! main challenge is to make is touch devices friendly, that is what I was experimenting with even if my implementation is buggy :)

I will close this issue and follow up in #69
