With the theme builder (code editor), you can edit your theme layout by getting access to the raw code for it.
How to access the Code editor?
In order to access the code editor, head over to the Appearance section on your Dukaan dashboard and click on Themes.
Now, click on Cutomize on for your particular theme. You will see the Code editor option. Click on it.
This will open the code repository for that particular theme as you can see below.
On the left side, you will see the repositories for the code files:
Public - Access of the public data that you can edit using the theme editor. This includes data about your products, categories, customers, etc.
You can make changes to your theme files as you may see fit.
Once you have made the changes, you can click on the Preview button to view these changes and click on Publish to make them live on your site.
