If you've published a page on Adobe Portfolio, you have the option to share the Page as a Project to Behance.
Upon publishing your site or updating your live site (by clicking on the green button on the floating remote toolbar), an overlay will appear listing the most recently published pages. You have the option to select individual Pages you wish to share as Projects to Behance.
If you published a Page on Adobe Portfolio and chose not to share to Behance at some point but wish to publish that Page now, you can do so by going to Manage Content located on the left side toolbar > then click on the gear icon located to the right of the page title > click "Share to Behance".
PLEASE NOTE: If your Page contains a Contact Form, it is not shareable to Behance.
