Hello,
If the design has been heavily customized, identifying the original pre-built demo can be a bit challenging. However, you can try the following methods to determine which Woodmart demo was used:
Navigate to Woodmart > Import Demos and see if any information is available about previously imported demos.
Like this: https://ibb.co/wxK2jSg
Navigate to Templates under the respective builder and compare with Woodmart demo layouts. This may help identify the demo used.
But Unfortunately, there is no direct way to detect the exact demo once major changes have been made, but these steps should help narrow it down.
Best Regards,
