Hello,
When you import a new demo after an existing one, WoodMart displays a warning message:
“WARNING! To import this demo version you need to remove all the previously imported content with all pages, products, and images. Do you want to remove the content and import this version?”
If you click OK, it will automatically remove the previous demo content before importing the new one. It gets the view of the demo and the existing content that you have added remains the same.
If you have multiple demos appearing, In that case, you can manually delete extra pages.
Navigate to Appearance > Widgets and Appearance > Menus to remove any extra elements from the imported demos.
Let me know if you need further assistance!
Best Regards,
