Custom layout for the multiroute balloon

Open in CodeSandbox

Object layouts can be created using the templateLayoutFactory factory and text templates.

This example creates a custom multiroute balloon layout that displays information about the selected route: each type of transport shows the route, the length of the route, and the travel time. The balloon layout is set via the multirouter option.
