Posted at

#はじめに
以下のようなセレクトボックス(値は20個ぐらい格納)を実装したので、備忘録として残しておきます。

#コード

create.blade.php
<div class="form-group">
    <label for="category-id">{{ __('カテゴリー') }}
    <select class="form-select" id="category-id" name="category_id">
        @foreach ($categories as $category)
            <option value="{{ $category->id }}" @if(old('category_id') == $category->id) selected @endif>{{ $category->category_name }}</option>
        @endforeach
    </select>
    </label>
</div>

値を保持するために
@if(old('category_id') == $category->id) selected @endif
と記述しています。
