I have same problem. But in console I have error: DbsvSelectedDatablocksContainerComponent.html:1 ERROR TypeError: Cannot read property 'add' of undefined at DefaultDomRenderer2.webpackJsonp.../../../platform-browser/esm5/platform-browser.js.DefaultDomRenderer2.addClass (platform-browser.js:2879) at BaseAnimationRenderer.webpackJsonp.../../../platform-browser/esm5/animations.js.BaseAnimationRenderer.addClass (animations.js:563) at DebugRenderer2.webpackJsonp.../../../core/esm5/core.js.DebugRenderer2.addClass (core.js:15027) at AngularDraggableDirective.webpackJsonp.../../../../angular2-draggable/angular2-draggable.es5.js.AngularDraggableDirective.ngOnInit...

It oddured in this case: ``` Selected datablocks ``` But everything work then: ``` Selected datablocks ```
