Hi,
You can get started by introducing a delete behavior in your domain model .

Also its important to note that once the object is deleted you have to make sure the associated object is not orphaned if you are planning to delete the object manually.
Thanks
My Team have given me the answer for future reference
You can controll this via a Flag/Field if this is global than one Field should be enough. If this is per User you need to assosiate this with the current user.
Example: add the field "Visible" in the entidy and set it to true per default. When you want to hide it, set it to false and in the list view you use a filter where Visible = true
