An object generator provides for creation of object(s) in an object hierarchy structure. In response to a command to expand a node/object, the object generator provides an initiator node that facilitates generation of a new object within the object hierarchy upon expansion of the node. A display component concurrently displays the initiator node with the expanded node. The initiator node used for creating objects placed (e.g., in-line) within an object hierarchy structure. To create a new object, an instruction (e.g., user input) to expand a node having a initiator node is received. By selecting the initiator node and entering a name, an object of type defined by the initiator node is created. For example, once the object is created the user can enter information defining parameter(s) of the object. Information can be entered through a user interface box (e.g., text box) that is displayed upon the creation of the object. Also, a grid can overlay the object hierarchy structure allowing information to be entered directly into grid cell(s). The grid can further be employed to display defined parameter(s).
