Dazzling - How to Remove the Last "." in the Navigation Menu
We’ve chosen to use “•” spacers between each one of the navigation menu options, but this leaves the very last item in your navigation menu with a hanging slash. To remove that you’ll want to make sure that you have enabled the CSS classes for your menu. You can do that by clicking on the Screen Options box in the upper right corner of your menu page.
Navigate to the last main line item in your menu (not the last item if it is a dropdown) and under the CSS class enter last then hit save!
