A page is accessed in a computer-based environment. A user interface gallery that includes at least one computer-based module from a remote source is opened on or in the vicinity of the page. The computer-based module can be inserted on the page from the gallery. The gallery can be dynamically populated with one or more computer-based modules from various sources remote to the page. A pointer that represents a computer-based module can be populated to the gallery as an alternative. The computer-based module can then be inserted on the page from the remote source when the pointer is selected and placed on the page. The computer-based module can also be stored in a database for future use after it has been inserted on the page.
