Option for order the already added collection

Hi there!
I’m using the latest version of the Omeka classic and using the items order plugin for ordering the items in a specific collection as required.
But is there any option to order the collections that are added already?
Thanks in advance.

You should be able to reorder any Collection you wanted to, please see the plugin’s instructions page.

Hi Daniele. Thank you for your reply.
Actually, I’m not talking about the items. Sorry for not being clear in the previous query.
I want to reorder the collection names in the collection tree.
To be more precise, the collection tree is getting arranged in the order we add a new collection. The last added one is coming at the end. But I want to see a newly added collection to be in somewhere in between of the existing tree.
