Deals > Order Categories By

Connect & Social
The API keys that the Twitter and Mailchimp widgets use. You can find.create yours on the official sites of the applications - https://apps.twitter.com/ and https://admin.mailchimp.com/account/api/
Setting Up the Menu
To customize the navigation menu go to Appearance > Menus and customize it as you'll normally do on a Wordpress site.
And don't forget to check the Theme Location at the bottom to be Sidebar Menu after creating your menu.

If you want to add additional pages to the menu like Deals or Categories click on Screen Options in the upper left corner of the page and check the types that you want to appear as selectables for the menu navigation.

When you are done, click Save Menu.
