Laravel使用数组并通过关联数组进行循环

Question

Consider I have the following array (passed to view from my controller):

'first' => [

    '1' => [
        'title' => 'First Div',
        'fields' => [
            'name', 'select'
        ],
    ],

     'divider',

    '2' => [
        'title' => 'Second Div',
        'fields' => [
            'address'
        ],
    ],

Looks like this in the browser when I dump:

array (size=2)
  1 => 
    array (size=2)
      'title' => string 'First Div' (length=9)
      'fields' => 
        array (size=2)
          0 => string 'name' (length=4)
          1 => string 'select' (length=6)
  2 => 
    array (size=2)
      'title' => string 'Second Div' (length=10)
      'fields' => 
        array (size=1)
          0 => string 'address' (length=7)

What I am trying to do is the following. I want to loop through all arrays, then display a div with a title, and within that div, loop through all the fields for each array.

For now I am focussing on just the looping through the array and displaying the right data, so without any divs yet. So something like this:

@foreach($first as $key => $value)

    // Unsure what to do here

@endforeach

I've tried a lot of things (just playing around trying to dump or echo out data), and I cannot even figure out how to display the title, let alone loop through all the fields values.

Either way, my ultimate goal is to create the following, dynamic view, based on what is passed from the controller:

To echo out a value in blade you can wrap your variable in {{ }}.

You should be able to do something along the lines of:

@foreach($first as $key => $value)

    <div>
        <h2>{{ $value['title'] }}</h2>

        @foreach($value['fields'] as $field)

            {{ $field }} <br>

        @endforeach
    </div>

@endforeach
