Drag&Drop no longer works on the layer panel

There is a Rhino API for Drag&Drop support - CRhinoDropTarget that allows plugin developers to capture drop events. However in Rhino WIP it seem that the layers panel is no longer a drop target
Dragging over the layer panel doesn’t call my SupportDataObject().

Is that feature removed ?

Hi @Nikolay,

Sorry I missed this.

The Layers panel has been rewritten in scratch.

Rhino 8 Feature: Layers Panel

Rhino WIP Feature: New Layer Visibility Control

Were just in the process of hooking up drag and drop and ironing out some issues.

You can track the progress here:


By the time Rhino 8 ships, this issue would be ironed out.
