Hello claysp5bg,
Thank you for your question on making doc files links in your menu. This is a normal WordPress function. When you add a new menu item to your menu, select the ‘Custom Links’ option. This allows you to name the link and point it to the correct document.
This will allow the user to download the document when they click on the menu option. If you want the document to open in the browser, you may consider pdf files instead.
Kindest Regards,
Scott M
