Hey I am trying to use the megamenu text option to add phone numbers to the locations listed in the footer of my website.
Hello @lacorte,
Thanks for asking. 
I am actually a bit confused with you question. Can you please elaborate the same?
Have you tried adding the contact numbers under X > Theme Options > Footer > Footer Content. You can also add contact information using widgets. You can do that from Appearance > Widget and add widget in Footer widget area.
Thanks.
The footer is being called through the menu widget. I want to put phone numbers under each location on the location footer links.

Hello There,
By default the footer menu is only 1 level and it does not display the menu description. This is also a WordPress standard. I brought this out because the menu description is a good way to display the phone numbers. You can check out this links if you want to pursue adding the phone numbers as a menu descriptions:
themefoundation.com/menu-item-descriptions/
On the other hand, the easiest way you can do it is to insert the phone number right after the menu item title. For example;
Barnegat, NJ <br> <small>1234567890</small>
Hope this helps.
Thanks! I really appreciate all your quick responses. This has to be the best support I have ever received on anyt heme!
You are most welcome as always!
We’re glad we were able to help you out.
Is there a way to better format the footer for mobile?
Please see attached on how it is displaying:

Hello @lacorte,
Thanks for asking. 
Please add following CSS under X > Theme Options > CSS let us know how it goes:
@media only screen and (max-width: 600px) {
ul#menu-footer li {
width: 45%;
margin-bottom: 15px;

}
