[Drag and Drop] Provide an input from where the preview will be attached #14559
Description
Bug, feature request, or proposal:
A new input to provide a DOM element to attach the cdkDragPreview element
What is the expected behavior?
Provide a new input to select a DOM element different than the body to attach the cdkDragPreview element
What is the current behavior?
There is no way to attach the cdkDragPreview item (default or not) to a different element than the body
What are the steps to reproduce?
- Start a dragging on an element
- The preview of the dragged element is attached as a child of the body
What is the use-case or motivation for changing an existing behavior?
We are using Angular as a dependency of an inner source project.. And we need to support different themes but the element where the preview is attached could make that the preview item doesn't looks like we expected on some projects because of their particular soluction
Which versions of Angular, Material, OS, TypeScript, browsers are affected?
We are using v7.1.1 of Angular and the rest of their dependencies
