What is the problem? I see your HTML is correct.

Use this new package:

"laravelcollective/html": "~5.0",

The in your views/templates use something like this:

{!! Form::model(
	$user,
	[
		'route' => ['admin.users.update', $user->id],
		'method' => 'PATCH',
		'class' => 'form'
	]
) !!}


<hr>

<div class="form-group">
	<input class="btn btn-success btn-block" type="submit" value="{{ trans('kotoba::button.save') }}">
</div>

{!! Form::close() !!}

Notice that the double and triple brackets have changed from L4.x

Where is that coming out in 1 big paragraph? In Sublime or within the view source of your browser?
