[Request] Allow empty values

[neoascetic]

Example use case: slider for price range selection for a filter in an online shop. When handles are set to their initial positions (most left and most right, respectively), "value" attribute of each corresponding form field must be empty. This means that user do not want to filter products by their price at all.

Interesting idea. How would you design the API for this?

[neoascetic]

I realized that this feature may be useful not only with serialization, so I've changed the title.
We may provide to slider user a one more setting, called "emptyOnEdges" or something like that.

In noUiSlider 4.3.0, you can use the new options in serialization to do this. I've written up an example, which you can view and edit here. Is this something like you had in mind?

[neoascetic]

Yeah, using callback for this is great. Thanks!

I have the same use case as the topic starter did.
Is the solution you provided in the fiddle still up to date?
