Hi,

The Metronic Laravel package you mentioned is actually a complete Laravel application and not just a library. It's designed to be a standalone application and cannot be directly integrated into an existing Laravel 7 project.

If you want to incorporate the Metronic template into your existing Laravel 7 project, you can use the HTML version of Metronic. You can download the layout partials from the Metronic layout builder and then integrate components like the header, footer, and menu into your existing Laravel project.

However, please note that this would require manual integration and might not provide the same level of seamless functionality as the dedicated Metronic Laravel package for Laravel 8.

Keep in mind that due to the differences between Laravel 7 and Laravel 8, direct integration might be complex, so the HTML version gives you more flexibility in this scenario.

Thank you
