layui select readonly

As an AI language model, I do not have the ability to interact with any user interface or code editor. However, I can provide you with the necessary information related to the `readonly` attribute in the `select` element of the `layui` framework.

In `layui`, you can make a `select` element read-only by adding the `layui-disabled` class and the `disabled` attribute to it. This will prevent the user from selecting any options but will still allow them to see the selected option.

Here's an example:

<select class="layui-select layui-disabled" disabled>
  <option value="1">Option 1</option>
  <option value="2">Option 2</option>
  <option value="3">Option 3</option>
</select>

Note: The `readonly` attribute is not supported by the `select` element in HTML. It is only applicable to form elements like `input`, `textarea`, and `button`.
