I have a script using components from the Elefront plugin, and it recently updated. When I pulled the update the old components turned into these ghost objects. They can’t be selected, moved, deleted, disconnected etc.
Any advice on how to get rid of them? I have them in both V7 and V8.
Thanks, Bathsheba
Select all none missing components, copy them, open a new file, paste the previously copied items onto the new canvas.
Yeah I know, but I don’t have to like it.
Are you sure? I’ve right-clicked them and found ‘delete placeholder’ - however it’s one at a time so if there are many I’d do what diff-arch said.
Sure, I don’t like the placeholders either. They are a pest.
Conceptually the idea is fine, however I don’t get why they can’t be simply moved or deleted.
Are you sure? This might be a windows or GH2 only thing?
In the latest version of Rhino for macOS you can’t move them, can’t remove them from groups, and can’t delete them. It’s really such a badly executed, half-baked concept.
oh wow, that sucks - yes I am using windows, but it’s regular grasshopper (not version 2) - maybe it’s on Rhino 8 for windows only 
this was for sure working on R7 around one month ago, and still works on R8 SR3

it just deletes all placeholders on the canvas
but be aware, there’s no “undo” 
The reason I didn’t find the right-click “delete placeholder” option, is that when the placeholder is in a group that option isn’t there.
Placeholders can’t be removed from groups because they’re not selectable, so it’s necessary to remove the group, delete the placeholder, remake the group.
Because some objects need to respond in a custom manner to delete or move actions, and since the object isn’t available to tell Grasshopper if anything out of the ordinary needs to happen I decided initially to make them readonly.
However I think now that was a mistake. The ability to get rid of them is more important than the slight risk of damaging the file.
