Laravel 5.4 dropdown default from database

Laravel we have more and more options Like drop-down selection from database records.

Take a simple example permissions and roles. I have to add a role with some permissions.

So I have to call permissions from the database.

RoleController:

$permissions = Permission::where('active_flag', 1)->orderBy('name')->pluck('name', 'id');

return view('roles.create',compact('permissions'));

 roles.create:

  <div class="form-group"> 

 {!! Form::label('permissions', 'Permissions:') !!} 

 {!! Form::select('permissions',$permissions, null,['id'=>'multiple-checkboxes','multiple'=>'multiple'] ) !!}

 </div>

Here I am using multiple dropdown.
Simply we can add roles with permissions.

Laravel 5.4 when migrating getting too long error

I can fix this by going in the migration for the user's table, and manually specifying the max-length of the email field, like so:

$table->string('email', 250)->unique();

As outlined in the Migrations guide to fix this all you have to do is edit your AppServiceProvider.php file and inside the boot method set a default string length:

use Illuminate\Support\Facades\Schema;
public function boot()
{
    Schema::defaultStringLength(191);
}
