Sections inside included blade templates - laravel

Question

I want to be able to add as many widgets as i want to a page.
To make it easier to visualize, here is what i want to achieve:
Master Page
Regular Page
In regular page, i want to call blade template panel as many times as i want. Of course, i would like to change sections inside each panel too.
Master Page
<div class="row">
<div class="col-lg-12">
<h1 class="page-header">#yield('title')</h1>
</div>
<!-- /.col-lg-12 -->
</div>
<!-- /.row -->
<div class="row">
<div class="col-lg-8">
#yield('panelsLeft')
</div>
<!-- /.col-lg-8 -->
<div class="col-lg-4">
#yield('panelsRight')
</div>
<!-- /.col-lg-4 -->
</div>
<!-- /.row -->
Panel Partial
<div class="panel panel-default">
<div class="panel-heading">
<i class="fa fa-{{ $panelIcon }} fa-fw"></i> #yield('panelTitle')
<div class="pull-right">
<div class="btn-group">
#yield('panelActions')
</div>
</div>
</div>
<!-- /.panel-heading -->
<div class="panel-body">
#yield('panelBody')
</div>
<!-- /.panel-body -->
</div>
<!-- /.panel -->
Regular Page
I want my regular page to extend master page, include as many panels as needed, and set sections of each of them. How can i achieve this?
I couldn't find an answer to this problem. Here is what i tried but it doesn't work:
#extends('layouts.content')
#section('title')
Dashboard
#stop
#section('panelsLeft')
#include('layouts.partial.panel', ['panelIcon'=>'flag'])
#section('panelTitle')
Current Projects
#stop
#section('panelActions')
<button type="button" class="btn btn-default btn-lg">
<span class="glyphicon glyphicon-star"></span> Create New Project
</button>
#stop
#section('panelBody')
<ul class="project-list">
{{ $projects }}
</ul>
#stop
#include('layouts.partial.panel', ['panelIcon'=>'user'])
#section('panelTitle')
Current Users
#stop
#section('panelActions')
<button type="button" class="btn btn-default btn-lg">
<span class="glyphicon glyphicon-star"></span> Create New User
</button>
#stop
#section('panelBody')
<ul class="user-list">
{{ $users }}
</ul>
#stop
#stop
