Is there a way that I can customize the customer portal through marketplace add-ons? Such as making the banner size small, adding more tiles within the same row, etc.
I am aware of below stated link but it does not helps as I need more customization.
However keep in mind that not that much customization can take place, due to security restrictions.
The app enables the Customer Portal customization and branding for elements such as banner, footer, background and many more.
It's the first version and we plan to add more features soon. We are open to feature ideas and feedback ✔️
