How to get data from db to layout in Laravel 8.* - php

Question

So I know how to retrieve data to views(using classes in controller)
but how can I return some data to layout which doesnt(or rather i dont know where they are) have its classes where i could get code to do so.
here is my form in which i would like to put cities name.
I always do it by giving to my frontend controller data from db using
$events = DB::select('select * from events');
return view('frontend/index', ['event' => $events]);
Edit
How to pass $city->id from loop to action?
My app.blade form:
<form method="POST" action="{!! route('cityView', ['id' => $city->id]) !!}" class="form-inline">
<div class="form-group">
<select name="city_id" class="form-control">
<option>xd</option>
#foreach(\App\Models\City::all() as $city)
<option value="{{ $city->id }}">{{ $city->name }}</option>
#endforeach
</select>
</div>
<button type="submit" class="btn btn-info">Search</button></a>
</form>
But how can I do it for a layout?
Would making a layout controller help with it? Or maybe make another class inside existing controller and return view of layout view?
Second solution would be adding this form to every single view since there will be only 3 of them but i prefer solution with app.blade

You can call data directly from layout something like this:
<form method="POST" action="#" class="form-inline">
<div class="form-group">
<select name="room_size" class="form-control">
<option></option>
#foreach(\App\Models\City::all() as $city)
<option value="{{ $city->id }}">{{ $city->name }}</option>
#endforeach
</select>
</div>
<button type="submit" class="btn btn-info">Search</button>
</form>
