you could implement it as behavior and just add it to the dropdown...
have a look at my example. the javascript is composed and written in the
"onRendered"
method so its written out right after the component.

this.options = options;

component.setOutputMarkupId(true);

public void onComponentTag(final Component component, final
ComponentTag tag) {
componentTag = tag.getName();
}
public void onRendered(Component component) {
String markupId = component.getMarkupId();
Response response = component.getResponse();
response.write("\n<script type=\"text/javascript\">\n");
response.write("<!--\n");
response.write("Nifty(\"");
response.write(componentTag);
response.write("#");
response.write(markupId);
response.write("\",\"");
response.write(options);
response.write("\");\n");
response.write(" -->\n");
response.write("</script>");
}
public void renderHead(IHeaderResponse response) {
response.renderCSSReference(new
ResourceReference(RoundedCorners.class, "nifty.css"));
response.renderJavascriptReference(new
JavascriptResourceReference(RoundedCorners.class, "nifty.js"));
}
}
