        $selects_names,
        $selects_languages,
        $selects_models,

    @if($selects_names)
    @foreach($selects_names as $key => $selects_name)
        @include(
            'treats.show_selects',
            [
                'name' => $selects_name,
                'language' => $selects_languages[$key],
                'model' => $selects_models[$key],
                'policy' => $selects_policies[$key]  ?? null,
                'show_type' => $selects_types[$key],
                'rank' => $selects_ranks[$key] ?? null,
            ]
        )
    @endforeach
@endif

and always get the above error most of my program is included from the code above they are treate function and now most of it now working

you can debug the array selects_names and see what is the format for accessing the array and do it like that. — Naveed Ali

Are you sure all the keys in $select_names exist in all the other arrays? Try to define a default value for the other arrays as you did for $select_policies and $select_ranks. And check this question — Prince Dorcis

Some key in $select_names is probably not in the other arrays. Define a default value for the other arrays as you did for $select_policies and $select_ranks:

[
    'name' => $selects_name,
    'language' => $selects_languages[$key] ?? '',
    'model' => $selects_models[$key] ?? null,
    'policy' => $selects_policies[$key]  ?? null,
    'show_type' => $selects_types[$key] ?? null,
    'rank' => $selects_ranks[$key] ?? null,
]
