Autocomplete In eBook Output

I created a Mobi eBook from a Zipped collection of HTML files. How do I add the Autocomplete feature we find in most mobi dictionaries? Are there some tag to include in the HTML files to make this possible.

This is needed so that users can use there search box to enter header titles that are automatically suggested and then have this titles linked to the section of the Mobi document with such heading.

I will appreciate your help and suggestion on this.

Thank you
