As written in the WordPress documentation:

A shortcode is a WordPress-specific code that lets you do nifty things with very little effort. Shortcodes can embed files or create objects that would normally require lots of complicated, ugly code in just one line. Shortcode = shortcut.. (From https://en.support.wordpress.com/shortcodes/)

Some shortcodes can accept one or more parameters, depending on the purpose.

It’s important to respect the shortcode syntax [shortcode_name parameter1=”parameter1_value” parameter2=”parameter2_value”].

Where shortcode_name is the name of the shortcode, parameter1, parameter2 … are the names of the parameters. Be careful to put the parameters’ values parameter1_value, parameter2_value … inside double quotes.
For more details, you can read the WordPress documentation at https://codex.wordpress.org/Shortcode.

The most part of the Freesoul shortcodes are completely integrated with Freesoul Builder, this means that while you are editing something using the Freesoul Builder editor, it will be possible to set the Freesoul shortcodes parameters using an easy and user-friendly graphic interface.

You could need to manually write the Freesol shortcode parameters just in case you are editing some content related to external plugins to whom it’s not possible to use the Freesoul Builder editor.

To know how you can manually write a Freesoul Builder element shortocde, just click on “CLASSIC MODE” on a page where it’s included that element.

In the pictures above you have on the left the Contact Form element as it is displayed when the Freesoul Builder editor is active and on the right the shortcode classic syntax.

If you need to know about WordPress built-in shortcodes visit: https://codex.wordpress.org/Shortcode. About Freesoul Builder shortcodes, it’s very easy, as said you have a graphic interface in the Freesoul Builder editor, where you can see all the available elements (based on shortcodes).

Here you have the Freesoul shortcodes that are not available as  Freesoul Builder elements.

You can use them inside your texts or wherever you need them.

For each shortcode, you can see a short description and the accepted parameters.
