I tried to use the Slider in my project.
When I tried to drag it using Chrome developer environment with device emulation turned on the tool-tips showing the current value are visible, but I cannot drag it.
When I tried the very same project on my IPhone, I can drag it perfectly but the tool-tips don't show up, so I can't see the value.
Any help will be very much appreciated.
I found out that using the attribute does the trick and it actually works on touch devices like my IPhone 6s . This is remarable because tooltips don't work on buttons using gwtbootstrap3. Actually they work but they take the first tip to show up. So you need to tip twice on a button which is not good.
