The Retail theme has support for the One Click Demo Import plugin.
If you do not already have this plugin installed and activated, you can do so by going to
Plugins > Add New and search for ‘one click demo import’.
Import all content, widgets and customization
Once the plugin is installed and activated, go to
Appearance > Import Demo Data and click the ‘Import’ button to begin the import of the Retail theme demo content and customizations.
Import either content or widgets or customizations
Should you want to import the demo content but not the theme customizations (styling) or widgets, you should switch to manual import to import the relevant file.
The relevant demo files are available to download here;
