Just pass the disabledin the options. Try with -
只需disabled在options. 尝试 -
{!! Form::select('pet_type', ['Select Type','dog', 'cat'], 0, ['class' => 'form-control', 'disabled' => true]) !!}
You can do it manually looping through the array in php or by using jquery.
您可以手动循环遍历 php 中的数组或使用 jquery。
$('select.someclass option:first').attr('disabled', true);

Looking through source, it looks like it's not possible. The <select>element is built up at https://github.com/illuminate/html/blob/master/FormBuilder.php#L532
查看源代码，看起来这是不可能的。该<select>元素建立在 https://github.com/illuminate/html/blob/master/FormBuilder.php#L532
The only args passed is the value, the name and the selected boolean. It looks like you have 2 solutions. Use javascript (argh), or use something like str_replace.
唯一传递的参数是值、名称和选定的布尔值。看起来您有 2 个解决方案。使用 javascript (argh)，或使用类似str_replace.
<?php
$field = Form::select('pet_type', ['Select Type','dog', 'cat'], 0, ['class' => 'form-control']);
// find value="Select Type" and replace with value="Select Type" dialled
echo str_replace('value="Select Type"', 'value="Select Type" disabled', $field);
?>

This might not be exactly what you are looking for but it will prevent user to select the first option but still be in the list.
这可能不是您要查找的内容，但它会阻止用户选择第一个选项但仍位于列表中。
Form::selectsupports A Grouped Listand you can use it this way.
Form::select支持A Grouped List，您可以通过这种方式使用它。
{!! Form::select('pet_type', ['Select Type' => ['dog', 'cat']], 0, ['class' => 'form-control']) !!}

The last array is used to form attributes of html tag, so you simple pass disabled into it:
最后一个数组用于形成 html 标签的属性，因此您可以简单地将 disabled 传递给它：
{!! Form::select('pet_type', ['Select Type','dog', 'cat'], 0, ['class' => 'form-control', 'disabled' => 'disabled']) !!}
