Is it possible to copy an entire page from one Webflow project to another project? How can this be achieved? Should I duplicate the project and set up a new custom domain?

Yes, it is possible to copy an entire page from one Webflow project to another project. There are a few ways you can achieve this:

1. Export and Import HTML/CSS: If you only want to copy the design and code of the page, you can export the HTML and CSS code of the page from the source project and then import it into the destination project. To do this, you can go to the source project and export the code by selecting the page and choosing "Export" from the settings menu. Then, in the destination project, create a new page and import the exported code by choosing "Import" from the settings menu. Keep in mind that this method will not copy any dynamic or CMS content, only the static design and layout.

2. Copy and Paste Elements: If you want to copy specific elements or sections from one page to another, you can simply select the elements or sections you want to copy in the source project, copy them (Ctrl+C or Command+C), and then paste them (Ctrl+V or Command+V) into the desired location in the destination project. This method allows you to copy both the design and content of the selected elements, including dynamic and CMS content.

3. Using Webflow's Team and Project Transfer: If you have multiple projects within your Webflow team account, you can use the Team and Project Transfer feature to move or copy an entire project, including all pages, assets, and settings, to another project. This method is useful if you want to transfer an entire project or make a duplicate of it. To do this, go to the source project's settings, click on "Transfer," and follow the instructions to transfer the project to the destination project.

Regarding the custom domain, duplicating the project alone will not automatically set up a new custom domain. You will need to configure the desired custom domain in the destination project's project settings separately. Keep in mind that if you're copying a project or duplicating it, you might need to update any absolute links or references within the project to ensure everything works correctly in the new context.

I hope this helps! Let me know if you have any further questions.
