To create a dropdown in Laravel, you can use the Laravel collective package which provides easy ways to create HTML elements. You can create a dropdown using the Form class provided by Laravel collective. First, include the Laravel collective package in your project.

This will generate a dropdown element with the specified options.
How to fetch data from a database and populate a dropdown in Laravel?
To fetch data from a database and populate a dropdown in Laravel, you can follow these steps:
Step 1: Create a model for the data you want to retrieve from the database. For example, if you have a "Category" model, you can create it using the following command:
1
|
php artisan make:model Category
|
Step 2: Define a route in your routes/web.php file to handle the request to fetch data from the database. For example:
1
|
Route::get('categories', 'CategoryController@index');
|
Step 3: Create a controller to handle the logic of fetching the data. You can create a controller using the following command:
1
|
php artisan make:controller CategoryController
|
In the CategoryController, define the index method to fetch the data from the database and return it to the view:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
namespace App\Http\Controllers; use App\Models\Category; use Illuminate\Http\Request; class CategoryController extends Controller { public function index() { $categories = Category::pluck('name', 'id'); return view('dropdown', compact('categories')); } } |
Step 4: Create a view to display the dropdown and populate it with the data fetched from the database. For example, create a dropdown.blade.php file in the resources/views folder:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
<!DOCTYPE html> <html> <head> <title>Dropdown</title> </head> <body> <select name="category"> @foreach($categories as $id => $name) <option value="{{ $id }}">{{ $name }}</option> @endforeach </select> </body> </html> |
Step 5: Finally, run your application and navigate to the route you defined in step 2 (e.g., /categories) to see the dropdown populated with the data fetched from the database.
That's it! You have now successfully fetched data from a database and populated a dropdown in Laravel.
