   @mcgilman I have a question. In the deletion of a multi-selection, why after the snippet is removed we loop the components of the snippet and remove them one by one ? 
   
   ```
    // remove all the non connections in the snippet first
                               components.each(function (ids, type) {
                                   if (type !== 'Connection') {
                                       nfCanvasUtils.getComponentByType(type).remove(ids);
                                   }
                               });
   
                               // then remove all the connections
                               if (components.has('Connection')) {
                                   nfConnection.remove(components.get('Connection'));
                               }
   ```

   Thanks for the feedback,
   
   @thenatog that's strange, I have been facing some problems with whitespaces recently, I will try to double check them using vi and notepadd++ 
   
   @mcgilman your points are spot on. I tried to tackle both points at first but wasn't successful, though to myself that I can divide the work into two jira tickets. but I agree to get all things done in this ticket. I am currently working on refactoring to make use of the common code as much as possible and at the same time make the message appear when multi-select.

Review comment:
       The whitespacing on this section of code has gone wrong. Can we update the whitespace to align with the rest of the file?

   The snippet can contain components of any type on the canvas. There are different objects responsible for managing each type of component. Once the server confirms that the snippet was removed, the UI needs to remove each one from the canvas. In this case, it's actually invoking each `remove` call with an array of ids of all components of each type that should be removed. Another thing to note, there is a behavior that if you delete a component on the server, it also deletes all outgoing connections. There's another loop above the code you referenced that identifies outgoing connections of all components deleted to ensure they are also removed from the canvas.
