Copy&paste elements / clone Webflow project

Hi, I have three questions for you:

I would like to know if it is possible to copy elements (div etc.) from a project without first cloning it to my account (dashboard)?

Can I share my project with another person (with the possibility of editing) in a different way than cloning from Webflow Showcase?

Can I clone a project to my Webflow account from a different place than Webflow Showcase?

Thanks for the answers!
