Thank you for writing.
In order to achieve a similar layout, you can add two columns and three rows in RadMultiColumnComboBox
. Then, hide the header and leave only the weekdays visible in the popup.
Off topic, note that most of the forum threads are reviewed by Telerik representatives and sometimes we address the questions asked by our customers in the forums as well. However, a post in the forum doesn't guarantee you a response from the Telerik support team. Moreover, threads are handled according to license and time of posting, so for any further questions, we suggest you use a support ticket.
I hope this information helps. Should you have further questions I would be glad to help.
