```
public class OptionTag
extends AbstractHtmlElementBodyTag
implements BodyTag
```
JSP tag for rendering an HTML 'option' tag.
Must be used nested inside a SelectTag.
Provides full support for databinding by marking an 'option' as 'selected' if the value matches the value bound to the out SelectTag.
The value property is required and corresponds to the 'value' attribute of the rendered 'option'.
An optional label property can be specified, the value of which corresponds to inner text of the rendered 'option' tag. If no label is specified then the value property will be used when rendering the inner text.

    Description copied from class: AbstractHtmlElementBodyTag

    Throws:
    JspException
  - onWriteTagContent
```
protected void onWriteTagContent()
```
    Make sure we are under a 'select' tag before proceeding.

  - exposeAttributes
```
protected void exposeAttributes()
                         throws JspException
```
    Description copied from class: AbstractHtmlElementBodyTag

```
    Description copied from class: AbstractDataBoundFormElementTag
    Autogenerate the 'id' attribute value for this tag.
    The default implementation simply delegates to AbstractDataBoundFormElementTag.getName(), deleting invalid characters (such as "[" or "]").
