something like... in the view
像......在视图中
{{Form::open(array('url'=>'expense/add', 'method' => 'POST', 'class' => 'form-signin'), array('role'=>'form'))}}
<select id="expense_category_id" class="form-control">
@foreach($data['categories'] as $category)
<option value="{{$category->id}}">{{$category->name}}</option>

Controller:
控制器：
$data['categories'] = Category::lists('name', 'id');
If you are using the attributeCategory model controller:
如果您使用的是属性Category 模型控制器：
$data['categories'] = Category::get()->lists('name', 'id');
view:
看法：
{{ Form::select('expense_category_id', $data['categories'], null, array('class' => 'form-control') }}
For laravel5.3 use pluck.
对于 laravel5.3 使用 pluck。
$data['categories'] = Category::all()->pluck('name', 'id');Reference
$data['categories'] = Category::all()->pluck('name', 'id');参考
You can try.
你可以试试。

Or you can pass the categories from your controller like this:
或者您可以像这样从控制器传递类别：
$categories = Category::all();
And inside your blade generate the dropdown like this:
在你的刀片内部生成这样的下拉菜单：
{!! Form::select('category', $categories->lists('name', 'id'), Input::old('category'), ['class' => 'form-control']) !!}
