Data Source Mappers are essential components within the Twidget no-code API platform, designed to facilitate the integration of dynamic data sources with UI elements. They serve the purpose of linking data source attributes to the respective fields required by UI components such as dropdowns, radio buttons, and navigation elements.

Dynamic Data Source: In Twidget, UI elements can utilize dynamic data sources instead of static data to populate their options. This enhances the flexibility of applications by enabling them to respond to live data.
Field Mapping: Field mapping allows developers to specify which attributes of a data source object correspond to the various fields needed by UI components. This includes defining label, value, and visibility settings for options.
Data Source List Object: This refers to a structured collection of objects, each typically containing attributes like label, value, and visible. The list itself serves as the data pool from which UI components derive their options.
Dropdowns and Navigation Elements: These UI components, by default, are set to utilize manual data entries. However, through Data Source Mappers, they can be configured to draw from a defined variable, thus leveraging the attributes of the data source list.
Field Mapping Section: Within Twidget, the configuration interface provides a field mapping section where developers can connect specific data source attributes to the expected fields of the UI components. Although default mappings are provided (e.g., label, value, visible), these can be customized based on the developer's requirements.
The process begins with defining a data source list that contains relevant objects. Developers then configure UI components such as dropdowns or navigation elements to use this list as their data source. By setting up the correct field mappings, the components will appropriately display data driven by the specified attributes of the data source, ensuring that they are dynamically updated and contextually relevant to the application's needs.
In summary, Data Source Mappers are crucial for transforming static UI elements into dynamic interfaces that can adapt according to live data, greatly enhancing the interactive capabilities of applications built on the Twidget platform.
