Using the theme editor
The theme editor is a tool for changing and previewing theme settings in real-time. Merchants access the theme editor by clicking Customize for a theme on the Themes page of their Shopify admin.
Editing theme sections
You can choose the type of content to display in a theme by using sections, which are Liquid template files. Sections define the elements of a page layout, such as slideshows, text blocks, newsletter signups, and collection images.
Editing theme settings
If you're a theme author, you can edit
settings_schema.json to create or change options in the theme editor:
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 theme editor are saved in
settings_data.json in the
config directory of their store theme.
