This package is based on nova-tabs to make it more like resource navigation tabs instead of tabs just for relations.

In other words, the way of displaying panels and relations in tab content is the same like for normal resource. The only difference is that there are navigation menu.

No changes needed regarding nova-tabs usage.

Keep in mind that you can use ->withToolbar() on Tabs instance if you want to display toolbar (resource edit button and resource actions) in case that Tabs instance is the first field in your resource fields definition.

<?php

namespace App\Nova;

use Eminiarts\Tabs\Tab;
use Eminiarts\Tabs\Tabs;
use Eminiarts\Tabs\Traits\HasTabs;
...

class Customer extends Resource
{
    use HasTabs;
    
    public function fields(Request $request): array
    {
        return [
            Tabs::make('Client Custom Details', [
                Tab::make('Information', $this->informationTabFields()),
                Tab::make('Sales', $this->salesTabFields()),
                Tab::make('Orders', $this->ordersTabFields()),
                Tab::make('Contact', $this->contactTabFields()),
                Tab::make('Finance', $this->financeTabFields()),
            ])->withToolbar()
        ];
    }
     
    ...
