By default, Avada will always show the top parent page of your side navigation set. If you would like to disable that, use the custom CSS below. Copy and paste it into the CSS field in theme options. This will also hide the first second level page of a parent/child page.
Please note this is a customization that is outside of what we can provide for theme support. If you perform the customization, you will need to maintain the changes for future updates and also be able to troubleshoot any issues that arise.
