Looking to access your theme's code or language options with Shopify's new theme editor layout?
In your Shopify admin click on Online store > Themes
Next to the theme that you want to edit click on the Menu button which is a small square with 3 blue dots
This will open a submenu of options which includes: Edit HTMl / CSS and Edit Language
So what is a preset
A preset is the same theme you have purchased but with different options enabled, different colors, fonts and different layout settings configured.
What you see in one preset is available for all of them. Using the options supplied within the theme we created multiple layouts and styles.
How do i switch between presets?
From your store admin click on: Online store > Themes > Customize Theme
At the top of the right sidebar click on Presets, you will see this:
Click on the Preset you wish to use - note this does not switch to a different theme and all changes you have made on the exsiting preset to this point will not be saved... To make sure you do not lose any changes click on Save current as new preset Name it and include a date - this will help you return if you need to.
So when i purchase a theme i receive all presets
Yes, presets are not separate themes, they are the same theme built using the same options but different choices and content made within each preset.
