Where I can get layouts to import in this plugin?

@saiful96, You can easily Export json file from https://productlayouts.wptoffee.com and import the json file to this plugin.

1. Go to https://productlayouts.wptoffee.com
2. Click any layouts which one you need.
3. You will see layouts list and Export button under every layouts.
4. Click Export button. This will download a json file.
5. Import the json file from this plugin.
that’s it.

Thank you.
