A server transmits a first page to be displayed. The first page includes a location entry representing a location to visit on a trip and at least two map elements, the two map elements and location entry being organized as a list in a first order on the first page. A request to move a selected map element of the two map elements within the list is received. Parameters of the selected map element are changed to form changed parameters that change the position of the selected map element within the list. The server transmits a second page to be displayed based on the changed parameters, the second page comprising the location entry and the two map elements organized as a second list in a second order.
