Tag system - Search by tag at click Laravel

I want to make a search function by tags. When a tag is clicked, to show me all the content with the value from tag ( like model, tag1, tag2 etc. ). For that, I make a page and tested if this can displays what I need. With ->where('tag', '=', 'model') I got all posts with `tag = model'. But now, I need to display based on what tag is clicked. So, here is what I have in single-news :

These tags are generated by this code:

<div class="container">
            <label>Tags

              <a href="{{ url('') }}">
                  <input class="input-tags" type="text" data-role="tagsinput" value="{{ $news->tag }}" disabled>
              </a>


              </label>
            </div>

        </div>

Here is my controller at the moment:

public function newsTag()
        {

                $data = $this->data;



                $data['news_details'] = News::with('category_name')->where('locale','=',Session::get('locale'))->where('tag','=','model')->orderBy('created_at', 'desc')->get();


                $data['categories'] = Category::with(['news' => function ($q){
                        $q->orderBy('title', 'asc');}])->where('category','=','news')->where('locale','=',Session::get('locale'))->get();

                // $data['categories'] = Category::with('news')->where('category','=','news')->where('locale','=',Session::get('locale'))->get();

                $data['instanews_details'] = InstagramNews::where('locale','=',Session::get('locale'))->where('category','=','news')->get();

                // $displayitem = DisplayItem::where('slug','=',url('project'))->first();

                // $data['page'] = $displayitem;
                // date_default_timezone_set('Asia/Kolkata');
                // // return $date = date('Y-m-d H:i:s');
                // return $date = strtotime('-1 hour');
                // echo 'John visited last ' . $date;

                $data['title'] = trans('fab.news');;

                $data['breadcrumb'] = 'news';

                // $data['menu'] = $tag->title;

                $data['metadescription'] = "news";

                $data['metatitle'] = 'news';

                // $data['blogs'] = $tag->blog;

                return view('news.news_tag',$data);

        }

Here is my route:

Route::get('news_tag', 'ModelController@newsTag');

Here is my page for results - news_tag.blade.php:

@extends('layout.front.template')
@section('content')

So, to conclude, I need to make this search function based of the tags from single news of every news. So, If news with id 1 has tags - test, tag, me, phone, and I press on tag, I want to be redirected to news_tag page, and to get only posts with tag on column tag from table News.
