Jquery Autocomplete and Auto Suggest

How do you stop the auto suggest feature from dropping down suggestions while using jquery autocomplete. The 开发者_开发技巧auto suggest is dropping down over the autocomplete selections. Its terribly annoying. I've tried z-index. Nothing seems to stop it.

Most browsers support the autocomplete attribute on html input elements.

<input name="textBoxWithoutAutoComplete" autocomplete="off" value="This textbox won't have autocomplete" />
