UI Builder can be used by application developers with a variety of
skill levels. We recommend developers with a high level of experience, sometimes referred to as
pro-coders, perform the procedures in this section.
* **[Configure components and repeaters (advanced feature)](https://servicenow-prod.fluidtopics.net/fJ2ZR~1meZrGM5nHCFjDZg)**   
  You can add and configure components as you build pages in UI Builder. You can also use repeaters to repeat components or multiple components with results from a data resource.
* **[Dynamically expose data in UI Builder pages (advanced feature)](https://servicenow-prod.fluidtopics.net/L~6cRs4KlJY_GTLaEaXA4A)**   
  Sync data between ServiceNow tables and data with the pages you build with UI Builder. Pages display synced data in real time and update data/tables when a user inputs information.
* **[Edit code with the Now Code Editor (advanced feature)](https://servicenow-prod.fluidtopics.net/cDT7EgC~NYIZ3c7G_9FFEg)**   
  Now Code Editor is a rich-text editor like interface that supports Cascading Style Sheets (CSS), Hypertext Markup Language (HTML), JavaScript, Extensible Markup Language (XML), and JavaScript Object Notation (JSON). Use Now Code Editor to modify UI configuration, data resource configuration, styles, events, client-side and server-side scripts in Next Experience UI Builder components.
