To add tabs to the frontpage, you will need to create a subpage to frontpage and give it a name of your choice. Then, add subpages to this newly-created subpage. These sub-subpages will be displayed as a tab on the frontpage, with the content from the WYSIWYG editor displayed in the tab.
Add as many subpages to “Tabs” as you like, depending on the number of tabs you want on the frontpage, and StoreFront will take care of the rest! For information on displaying products from WooCommerce or other posts in the tabs, read-up on using our News Show Pro widget as a shortcode here.
Settings connected with the slider may be found in Template Options -> Frontpage tab.
