Open Document Outline by Default in Browser

[defaultx21xzvmhgwu7]

Apologies if this is the wrong forum. I have a number of documents that are created in Word and exported to PDF, then hosted/viewed online. I have no trouble creating the document outline in Reader (online and offline) by using Word's heading styles, but I'm wondering how to force a PDF to show that outline by default (the default in Reader and most browsers seems to be that it's toggled off). I have found other PDFs online that have this function, so I know it's possible, but I can't seem to find documentation on how.

Thanks!

Does you mean the bookmarks?
