When registering controls in Kirki, they are saved as theme_mods by default.

If you choose to save your settings as options, you can do so by passing the option_type argument to all controls like so:

'option_type' => 'option',

When switching the option_type from theme_mods to option, it is important that you also pass an option_name to keep things organized. If no specific option_name is given, the settings value will be used as the option name.

In the example below, the first 2 color fields will save their values in a single option (all_my_options). The third control will save a separate option in the database named my_standalone_option while the 4th example doesn’t specify an option name and therefore will use kirki_demo_color_hex_3 as the option name.

/**
* Value will be saved under 'all_my_options' in the database.
*/
