User-configurable aggregate web components

Database systems and methods are provided for visual design and customization of processes for web applications. A method involves providing a page builder graphical user interface (GUI) display at a client device over a network, obtaining a configured set of configurable web components added to an aggregate component region on the page builder GUI display, generating behavioral code corresponding to the configured set of configurable web components, generating presentation code corresponding to a spatial arrangement of the configured set of the configurable components within the aggregate component region, creating an aggregate component object in a database to maintain an association between the presentation code and the behavioral code for the configured set of the configurable components, and updating code for the web page to include a reference to the aggregate component object at the aggregate component region of the web page.
