With PixCodes you can have a shortcode insert interface for the WordPress Classic Editor.

PixCodes is intended for Classic Editor and TinyMCE workflows. It does not add a block editor interface.

The awesome part is that you can filter any shortcode parameters or overwrite any shortcode template with your theme.

Note: this plugin does not add any style to the output of shortcodes.

We believe that shortcodes functionality should be offered by a plugin and the style should be provided by themes.

Here is a detailed documentation about how you can configure some plugin settings and output.
