Code builders can be used to generate code segments that are customized in response to user input. An integrated development environment provides links to one or more code builders that are configured for developing specific types of code. Once a code builder is selected or dragged and dropped on a code editor, a code builder interface is launched that prompts the user for input that will be applied to a document object model describing the basic attributes of the code segment. The code builder then generates the customized code and inserts it into a desired location within the integrated development environment.
