The theme editor is a tool for changing and previewing theme settings in real-time. Merchants access the theme editor by clicking Customize theme for a theme on the Themes page of their Shopify admin.
All themes include a
settings_schema.json file in the theme's
config directory that specifies the theme settings that appear on the Customize theme page.
Editing theme settings
If you're a theme author, you can edit
settings_schema.json to create or change options on the Customize theme page:
settings_schema.jsonfile in the
configdirectory of your theme. Follow the specified format.
Edit your other theme files to access the settings that you've defined.
Theme settings that a merchant configures using the Customize theme page are saved in
settings_data.json in the
config directory of their store theme.
