How to Set a Portfolio Project item as Draft
Squarespace doesn't have a built-in draft mode for portfolio projects, but you can achieve this by using the Ground Control plugin.
Install Ground Control: Activate the Draftify Portfolio feature.
Set the Project as Draft:
Open your portfolio project.
Click the three-dot icon next to the item.
Choose "Set as Draft" to hide the project from visitors and portfolio page.
For detailed instructions, check out the Draftify Portfolio Guide.
