[BlockLab](https://resources.symphonycommerce.io/knowledge-base/blocklab?hsLang=en) # Why is there two of everything in BlockLab? Upon entering a BlockLab page, you may notice certain blocks appearing multiple times. This duplication is specifically related to the Mobile and Laptop views, which is why you will only see these duplicate blocks within the admin system and not on the front-end of your store. We know how odd some text can look when it's larger on mobile, or how strange carousels can appear on smaller screens. With this in mind, we created an option to hide or view certain blocks for Mobile, Laptop and Tablet. When in BlockLab, on the Block tab, you will see these three icons: ![](https://resources.symphonycommerce.io/hs-fs/hubfs/image-png-Apr-15-2024-08-48-54-6476-AM.png?width=113&height=68&name=image-png-Apr-15-2024-08-48-54-6476-AM.png) The first icon is Mobile, second is Tablet, and the third is Laptop/PC. If you select a block, for example an Image block, and click the Mobile icon, you will notice that on mobile this Image block will not show. This can also be done for Laptop and Tablet; when deselected, these items will be hidden on said device. Have a try and see! ![](https://resources.symphonycommerce.io/hs-fs/hubfs/image-png-Apr-15-2024-08-49-06-7468-AM.png?width=208&height=131&name=image-png-Apr-15-2024-08-49-06-7468-AM.png) - [Getting started](https://resources.symphonycommerce.io/knowledge-base/getting-started?hsLang=en) -
