Does Webix support rearranging of components/widgets within a layout dynamically using drag drop and also make each of them resizable?
The Portlets provide a possibility to rearrange views using drag-n-drop. Relative sizing will work as needed.
But we do not recommend to use the ui.resizer with portlets. Between them, the resizer acts as any static UI, i.e. irresponsive to DnD, but preserving its features.
