I was thinking this theme will have all the necessary shortcodes but there are none. Can you tell me, if i can use this theme to create a site like the above one? Or should i depend on external plugins, such as shortcodeultimate for such functionalities?
we don’t include shortcodes in the theme as this would lead to theme lock-in – if you ever felt the need to change theme then that content would be a mess.
So if you need shortcoded content then a plugin would be correct.
Looking at that site, most of it is fairly straightforward and could be done with the Gutenberg Block editor.
