@behroozbc Hi, I'm open to looking at PRs but I'm unlikely to add this functionality myself.

@IeuanWalker hi
I want to help add this feature.
but I dont have any experiment to make Xamarin component Library
please help me

@behroozbc This probably isn't the best one to start with.

The 2 main files are -
- https://github.com/IeuanWalker/Xamarin.Forms.CustomSwitch/blob/master/Src/Switch/CustomSwitch.xaml
- https://github.com/IeuanWalker/Xamarin.Forms.CustomSwitch/blob/master/Src/Switch/CustomSwitch.xaml.cs

To support this feature IsToggled would need to be changed to allow nullable (i.e. if the null set position to the middle).

Issue i have with this is this will be a breaking change, so may be best to duplicate the current control to add this functionality.

Once IsToggled is nullable, you'll need to update the loaded event to set the position of the toggle to the middle if null

Is better make new component for multi step not only 3 step like below? and fix breaking change issue.

all user don't want 3 step and more

@behroozbc That's a different type of control altogether. It's called 'Segmented control'. There is a PR in the Xamarin.CommunityToolkit that implemented it so you could just copy the code for now, or look for another package that is already released to NuGet for it.

The original idea above is called 'Indeterminate switch'. It's not very common and I haven't had a need case for it yet. So I am open to PR for that, but not the segmented control, as it isn't a switch.
