Sometimes, I need to present a dynamic list bound to a dataSource. I believe ListView is the widget for that.

However, ListView adds role="listbox" to the root element and role="option" to children.

Per https://www.w3.org/TR/wai-aria-1.1/#listbox , a listbox is a widget that allows to select an item. A non-selectable ListView should have role="list" and its children should have role="listitem".

Bug report

The Kendo UI ListView widget is not rendering a vertical scrollbar when the scrollable option is set to "endless" and the content overflows out of its wrapper.

Reproduction of the problem:

1. Set the scrollable option to "endless".

2. Dojo sample for repro:
