Creating Custom Shortcodes Button in WP TinyMCE Editor

Hi Guys

New to the game. Can anyone provide a link to an article or tutorial where it shows how to create a custom shortcode button in-built into the wordpress article editor to insert styles such as tables, dropcaps, layouts, lists, pricing tables…(and many more of my choice), and for it to be added when a theme is installed.


Here you go -

All the best,


Great, Many thanks!
