Navigate database/migrations/ and open create_categorys_table.php file. Then update the following code into this file:

use Illuminate\Database\Migrations\Migration;

class CreateCategoriesTable extends Migration
     * Run the migrations.
     * @return void

        <div class="container" style="margin-top: 50px; margin-left: 300px">
            <div class="row">
                <div class="col-lg-6">
                    <form action="">
                        <select class="browser-default custom-select" name="category" id="category">
                            <option selected>Select category</option>
                            @foreach ($categoris as $item)
                            <option value="{{ $item->id }}">{{ $item->name }}</option>
                        <select class="browser-default custom-select" name="subcategory" id="subcategory">
        <script type="text/javascript">
                headers: {
                    'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
            $(document).ready(function () {
                $('#category').on('change',function(e) {
                 var cat_id = e.target.value;

                       data: {
                           cat_id: cat_id
                       success:function (data) {
