            <option value="ZM">Zambia</option>
            <option value="ZW">Zimbabwe</option>
        </select>

Now I am trying to edit the country, Say in table value is stored UK for United Kingdoms, then how can I keep selected the United Kingdom based upon the country code in the table.

Writing If condition for each option seems not to be a feasible option, I know laravel facade Form::select() which can deal with this easily, but without using If condition and Form Facade is there any way of achieving this.

    <select name="country" id="country" class="form-control">
    <option value="AF" {{ (isset($user->country)&& $user->country=='AF')?'seected':''}}>Afghanistan</option>
    <option value="AX" {{ (isset($user->country)&& $user->country=='AX')?'seected':''}}>Aland Islands</option>
    <option value="AL" {{ (isset($user->country)&& $user->country=='AL')?'seected':''}}>Albania</option>
    <option value="DZ" {{ (isset($user->country)&& $user->country=='DZ')?'seected':''}}>Algeria</option>
    <option value="AS" {{ (isset($user->country)&& $user->country=='AS')?'seected':''}}>American Samoa</option>
    </select>
    

    Better way is keep option value in array

    $countryList=[
        'AF'=>'Afghanistan',
        'AX'=>'Aland Islands'
        ];
    
    
    <select name="country" id="country" class="form-control">
    @foreach($countryList as $key=>$value)
      <option value="{{$key}}" {{ (isset($user->country)&&$user->country==$key)?'seected':''}}>{{$value}}</option>
        </select>

    I would do this.

    <select name="country" id="country" class="form-control">
                    <option value="AF" {{$customer->country=='AF'?'selected':null}}>Afghanistan</option>
                    <option value="AX" {{$customer->country=='AX'?'selected':null}}>Aland Islands</option>
