Thank you for contacting us.
We have checked the reported scenario. By default, the dropdown will open at the bottom. If there is not enough space to open the popup at the bottom then, the popup will open at the top. This is default behavior of popup components. To open the dropdown at top we suggest you use DropDownList open event, in that you can get the popupHeight and set a negative value into popup offsetY property. Please find the code snippet below
