How to implement data communication and DOM operation between gridster-item?

[ninggaoqian]

I want to implement data communication between two gridster-items. My business scenario is that I want a user

carrying information in a gridster to be dragged and dropped to a gridster-item with the function of a recycle bin, but how to communicate between two gridster-items to trigger the operation of deleting user information when dragging and dropping?

@ninggaoqian https://github.com/tiberiuzuld/angular-gridster2/blob/master/projects/angular-gridster2/src/lib/gridsterConfig.constant.ts
dropOverItems: false, // enable drop items on top other item
dropOverItemsCallback: undefined // callback on drop over another item
allowMultiLayer: false,

These options might work for you.
