Hi, I want to know how to make a slider move discretely rather than continuously. As an example, I want the slider to jump from 1 to 2 when I move it. In other words, I need to enable the "Snap to Tick" feature.
Thanks in advance.

In the same slider you posted, for example I want the slider handle sits on the tick intervals not between them. for example I want 1, 2, 3 ... rather than 1.48

In the callback make the slider value rounded and then set the slider position to this rounded value.

Is it what you expect? If you are using app designer, on your left hand side bottom, there is configuration you may edit. Empty the minor tick, and modify the major tick to 1,2,3,4,5.
Don't forgot to change the limit as well to 0,5

The only way i can think about it is to create a callback function, then use the round off method to readjust the value of slider if user move the handle to the place between intervals.
Create a callback function for your slider
value = app.Slider.Value;
app.Slider.Value=round( value / 20 ) * 20;
You may change the value of 20 to 2, if the interval is 2.
