如何在joomla 2.5文章选项中添加自定义字段？

Question

I want to add a custom field to the article options in joomla. It can be either in the "Article Options" or in a seperate form table. I just need on single checkbox. How can this be done? I searched in the web, but it's not possible to find a working solution.

EDIT: I need to add a custom field in the backend. I'm writing a simple plugin, where I show a js widget, when it's enabled in the article options. Therefore I need a custom field (checkbox), to check, if the widget is enabled for this article.

Go to

Add your Custom Field under the

<fields name="attribs">

Tag

<field 
     name="your_custom_field_name"
     type="list"
     label="YOUR_CUSTOM_FIELD_NAME"
     description="YOUR_CUSTOM_FIELD_NAME">
         <option value="">JGLOBAL_USE_GLOBAL</option>
         <option value="0">JNO</option>
         <option value="1">JYES</option>
</field>
