How to set validation as optional in Laravel

Question

I want to make roles to be available only for admin can select roles for users and while user wants to edit the profile information can only see his roles but can't edit his role how to make it roles field to be locked for users Following code :

<div class="form-group"> 
{{ Form::label('role', 'Roles', array('class' => 'control-label mb-1')) }} <br/> 
{{ Form::select('roles[]',$roles,$selectedRoles,['class'=>'myselect','data-placeholder'=>'Select role(s)', 'multiple'] ) }} 
</div>

Please include details on how that isn't working.

You may use the following

use Illuminate\Validation\Rule;
//..

if(!$request->filled('roles')) {
   $request->merge(['roles' => []]);
}

$this->validate($request,[
    'name' => 'required',
    'email' => 'required|email', //'required|email|unique:users,email',
    'password' => [ 'string', 'min:8'],
    'roles' => 'nullable|array', 
    'roles.*' => [Rule::requiredIf($request->filled('roles')), 'exists:roles,id'],  
],[
    'name.required' => "Name field is required",
    'email.required' => "Email Field is Required",

    'email.email' => "Invalid Email Format ",

    'password.min' => "The Password Must be at Least 8 Characters or More",
    'roles.*' => "The Role is Required",
]);

//...
