The Ella theme can display the current status of your shopping cart in the head of the website, on the right end of the main menu. This is optional, but requires a 3rd party plugin to function. The required plugin can be found here:
WOOCOMMERCE MENU CART PLUGIN
The standard version of this plugin is a free plugin and is all that is required for this theme.
Set this plugin up as follows:
Download, install and activate this plugin as normal.
In the WooCommerce item in the mian WP admin menu, you will now have a new sub item entitled "Menu Cart Setup".
In this page, select the Main menu at the top.
Check the "Always display cart, even if empty" option.
Check the "Display shopping cart icon" option.
The only available icons in the standard version of this plugin is the default icon. This is fine.
Set the menu item to display "Both price and items".
Set the alignment option to "Default Menu Alignment"
Now click "Save Changes" and that's it, its now setup and will appear in your site header as part of the menu.
The cart item created by this plugin is actually just an additional menu item in the main menu. Therefore on devices with small resolutions, the cart item can be found in the mobile menu dropdown, as the last item of the main menu.
