问题
I am currently developing an application using Kendo UI. I use a dropdownlist like this
Kendo UI dropdownlist
On the browser it work's fine. I can open the list an scroll with the mousewheel, but when I try to use it on a device with touch (tablet or smartphone) i cannot scroll in the dropdownlist.
How can i add a listener or something else on the dropdownlist, that this makes it possible to scroll?

From here:
Kendo Support Forum - Unable to scroll on iPad
To enable scrolling of the DropDownList ( popup in particular ) you need to include kendo.mobile.core.js, kendo.mobile.scroller.js. Check this jsFiddle demo, which shows how to enable scrolling in mobile device.
The css from the fiddle:
.km-touch-scrollbar {
position: absolute;
visibility: hidden;
z-index: 200000;
height: .3em;
width: .3em;
background-color: #333;
opacity: 0;
border-radius: 0.4em;
-moz-border-radius: 0.4em;
-webkit-border-radius: 0.4em;
-webkit-transform-origin: 0 0;
-moz-transform-origin: 0 0;
transform-origin: 0 0;
-webkit-transition: opacity 0.3s linear;
-moz-transition: opacity 0.3s linear;
transition: opacity 0.3s linear;
}
.km-vertical-scrollbar {
height: 100%;
right: 1px;
top: 0;
}
.km-horizontal-scrollbar {
width: 100%;
left: 0;
bottom: 1px;
}
.km-scroll-container {
-moz-user-select: none;
-webkit-user-select: none;
user-select: none;
-webkit-margin-collapse: separate;
}
.km-android .km-touch-scrollbar {
background-color: #33b5e5;
border-radius: 0;
-moz-border-radius: 0;
-webkit-border-radius: 0;
}
