Create form for the tasks:

<div class="col-md-12 mb-3">
    <label for="clientId" class="fw-bold">Client*</label>
    <select name="clientId" class="form-control">
    @foreach ($clients as $client)
        <option value="{{$client->id}}">{{$client->client}}</option>
    @endforeach 
    </select>
    @error('clientId') <small class="text-danger">{{ $message }}</small> @enderror
</div>

<div class="col-md-12 mb-3">
    <label for="Object1" class="fw-bold">Address*</label>
    <select name="Object1" class="form-control">
    @foreach ($clients as $client)
        <option value="{{$client->id}}">{{$client->object}}</option>
    @endforeach
    </select>
    @error('adressObject1') <small class="text-danger">{{ $message }}</small> @enderror
</div>

The idea is that I want in the address field to be shown only the address for the selected client and I also have trouble setting the foreign keys from the tasks table to the clients table. Here is the controller I made

<?php

namespace AppHttpControllers;

use AppHttpRequestsTasksFormRequest;
use AppModelsClients;
use AppModelsTasks;
use IlluminateHttpRequest;

class TasksController extends Controller
{
    public function index(){
        $tasks = Tasks::orderBy("created_at","desc")->paginate(10);
    }
    public function create(){
        $clients = Clients::all();
        return view("pages.tasks.create", compact("clients"));
    }
    public function store(TasksFormRequest $request){
        $task = new Tasks();
        $task->fill($request->all());
        $task->save();
    }
}

TasksFormRequest

<?php

namespace AppHttpRequests;

use IlluminateFoundationHttpFormRequest;

class TasksFormRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     */
    public function authorize(): bool
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array<string, IlluminateContractsValidationValidationRule|array<mixed>|string>
     */
    public function rules(): array
    {
        return [
            'dateOfMeasurement' => 'required|date',
            'mk' => 'nullable|boolean',
            'osv' => 'nullable|boolean',
            'sh' => 'nullable|boolean',
            'vent' => 'nullable|boolean',
            'klim' => 'nullable|boolean',
            'f-0' => 'nullable|boolean',
            'z' => 'nullable|boolean',
            'm' => 'nullable|boolean',
            'izol' => 'nullable|boolean',
            'dtz' => 'nullable|boolean',
            'wayOfShowingDocumentation'=> 'required|string',
            'certifaciteNumber'=> 'required|string',
            'nextMeasurment'=> 'nullable|date',
            'mkNext' => 'nullable|boolean',
            'osvNext' => 'nullable|boolean',
            'shNext' => 'nullable|boolean',
            'ventNext' => 'nullable|boolean',
            'klimNext' => 'nullable|boolean',
            'f-0Next' => 'nullable|boolean',
            'zNext' => 'nullable|boolean',
            'mNext' => 'nullable|boolean',
            'izolNext' => 'nullable|boolean',
            'dtzNext' => 'nullable|boolean',
        ];

    }
}

And the migration file:

<?php

use IlluminateDatabaseMigrationsMigration;
use IlluminateDatabaseSchemaBlueprint;
use IlluminateSupportFacadesSchema;

return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::create('tasks', function (Blueprint $table) {
            Schema::create('tasks', function (Blueprint $table) {
            $table->id();
            $table->date('dateOfMeasurement');
            $table->boolean('mk')->nullable();
            $table->boolean('osv')->nullable();
            $table->boolean('sh')->nullable();
            $table->boolean('vent')->nullable();
            $table->boolean('klim')->nullable();
            $table->boolean('f0')->nullable();
            $table->boolean('z')->nullable();
            $table->boolean('m')->nullable();
            $table->boolean('izol')->nullable();
            $table->boolean('dtz')->nullable();         
            $table->string('wayOfShowingDocumentation');
            $table->string('certificateNumber');
            $table->date('certificateDate');

            $table->date('nextMeasurement');
            $table->boolean('mkNext')->nullable();
            $table->boolean('osvNext')->nullable();
            $table->boolean('shNext')->nullable();
            $table->boolean('ventNext')->nullable();
            $table->boolean('klimNext')->nullable();
            $table->boolean('f0Next')->nullable();
            $table->boolean('zNext')->nullable();
            $table->boolean('mNext')->nullable();
            $table->boolean('izolNext')->nullable();
            $table->boolean('dtzNext')->nullable();
            
            $table->timestamps();
                        
        });
    });}

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::dropIfExists('tasks');
    }
};

Thank you in advance for the help!

I tried with

<option value="{{$client->id}}">{{$client->object}}</option>

to show the specific address for client but it lists all of the addresses
