We tested the jqxRibbon scrolling on an Android mobile phone and it works as expected. Please note, however, that to initiate the scrolling, you need to “taphold” one of the ribbon scroll buttons. Please share if you have encountered this issue on a device with different operating system and we will test the scrolling behaviour accordingly.
Do you mean that the scroll buttons are not shown (but are supposed to) or that they are shown, but are not responsive? Please note that you would have to add more items to the ribbon in the aforementioned demo in order to show the scroll buttons.
Thank you for your feedback. As I understand, the scroll buttons show up, but are unresponsive. We will investigate this behaviour and if we confirm it as an issue with jqxRibbon, we will fix it in a future version of jQWidgets.
