Hi Mark,
I have tested for this issue in v2.0.5.1 and this feature does exist in Syncfusion TreeViewAdv. Refer to the modified
TreeViewAdvDragDrop_sample. Drag any node in black and hover over ''Finland''. It will auto expand after a short delay. Please let me know the version of Essential Suite that you are using. We appreciate your interest in Syncfusion products.
