You have collection of Projects Object in the $projects after you perform a loop you get each project as $project depending on the state of the loop. When you call the projectitem It will return a collection of ProjectItem and not a single ProjectItem that is the reason why $id is undefined. You should form another loop to get each ProjectItem separatly

@foreach ($projects as $project) 

    // $project->projectitem() return a collection of projectitem 
    // and not a single projectitem
    // to access ID of each projectitem you must perform another loop

    @foreach ($project->projectitem() as $projectitem)
         // here project id is disponible as property accessible like this
         {{ $projectitem->id }}
    @endforeach
@endforeach
