By default, the categories and sub-categories in your app use the same thumbnail images as on the webstore. You are recommended to change those thumbnail images into icons that will be intuitive for customers, that is, those that are used in most applications. This will allow customers to quickly and efficiently navigate through your app.

Please log in to JMango360 Back Office > Design module. 

Your app's categories and other pages are placed in the Design module. To update a thumbnail image to a category, just click the image box associated with that category and select the image you want. 

 

Please select a category and navigate to the Settings tab. From here you can enable/disable the sub-categories under that parent category. You can also update the sub-category thumbnail image.
