To copy a collection, first the owner will have to have 'copy' enabled for that collection.
To enable copy on your collection:
- Open the collection in edit mode by clicking 'Edit Collection'.
- Click 'Enable Copy' in the top-right to toggle the setting on.
To copy a collection:
- Open the collection
- On the top bar, click 'Copy'.
- Enter a name for the copied collection, or keep it the same.
- Click 'Copy'.
And that's it! The collection will appear on your homepage. You can copy someone else's collections or your own, but either way the setting will need to be enabled by the owner first, for each collection.
