The Transformable Web Part is meant to take the functionality of a Pages+Repeater, and compress it into an easy to use no-coding-necessary Web Part. Primarily to create structured content for users where you don't really need special coding logic, you just want to give them a couple fields and then dictate how those fields are displayed via Kentico's Transformations.
A normal transformation takes an object on the tree and allows you to transform the object's values in a Transformation. This tool takes the Properties of your web part and allows you to transform these values in a Transformation.
Simply Clone, add your custom properties, and create your transformation, and you're set to go! Also supports "Multi Row" logic and skipping rows with missing data.
How to use it in the "Documentation" tab of the Web Part. Enjoy!
