GeoDirectory adds an Insert Shortcode button to the Classic TinyMCE Editor in WordPress. This button makes it easier to access shortcodes and add them to your posts and pages within seconds. 

However, if you do not wish to use this button, or have contributors and editors on your site who might accidentally use the button, you can use the following CSS to hide the button completely: 

.sd-lable-shortcode-inserter {display: none;}

Note that you will need a plugin such as Add Admin CSS in order to insert the above code. For details, please go through the plugin’s documentation.
