A computer system enables a user to conveniently fill-out, configure, and submit a structure of interrelated data fields, where the order and type of linking between the fields is user selected. A graphical user interface presents a field template having one or more data fields. The user may extend the electronic form by selecting an expand form field; in response to selection of the expand field, the user interface adds a second field template and a connective field to the display. This second template, like the first, includes one or more data fields. Using a connective field, the user identifies a logical relationship between the first field template and the second field template. For instance, the user may select from Boolean or other connective terms to construct a form having a complex format of interrelated fields. As each new field template is added with its corresponding connective field, the user interface also presents a nesting icon, allowing the user to establish a logical hierarchy between the various field templates.
