The toggle slider is a very common pattern on mobile devices for iOS and certain web applications, however they work well for only a dual-state switching. enter image description here

When it comes to more than two states, the interaction and behaviour for the sliding toggle breaks down, and the most common strategy is to implement a button group that has a toggle-like behaviour, such as the one below (also known as a segmented control for iOS):

The problems that I can see with sliding toggles that has more than two states are:

  1. How to indicate the different states/statuses unambiguously
  2. How to provide interactions with good affordance and ease of ease
  3. Whether there are better alternatives or if there are specific circumstances when this is the best pattern to solve the UI design problem.

Has anyone seen good examples of toggle sliders with more than two states implemented?

  • question: are you looking for a multi-state toggler with a single or multiple selected states? e.g. 5 states, but only 1 can be selected at a time; or 5 states but multiple states can be selected? – tohster Mar 26 '15 at 1:45
  • @tohster good point. I was initially just thinking of a single state, which is generally what the slider toggles are used for. I am happy to hear suggestions for both types of toggles as well, but perhaps I should ask another question. – Michael Lai Mar 26 '15 at 2:29

I've used Twitter Bootstrap button groups in the past for this same idea. Since they are actually buttons, and not parts of a slide, I don't think the selected states are confusing (and you can style them to be as unambiguous as you want).

I think the bigger question to ask is whether it meets your needs and what you are trying to solve by implementing this. Is this a scalable option for your project? Is there the possibility in the future of adding more states?

To be honest you probably shouldn't be using a toggle if you have more than 2 states - a toggle by it's nature is an either / or switch - that's why you're having this problem.

For your application it would depend on the number of states and the context, but most mobile OS handle drop lists very well. A series of Radio buttons would be another solution.

I agree with the aforementioned examples. You pretty much need radio buttons turned into slider. You can do that even with CSS like the image below.

A multi-state "toggle" is really a set of radio buttons styled as a single segmented button, as shown in @nachoproblem's images.

The problem with treating it as a "toggle" is that a physical toggle "slides" from one state to the next. With only two states, it "slides" from on to off or back again, which makes sense.

With four states, say, is it your intent that it would "slide" from 1 to 2, then from 2 to 3, then from 3 to 4? In that case, it's more like a volume control with detents. Or is it your intent that the user could choose any of the states, as in @nachoproblem's examples?
