Thank you for contacting us and I'd be happy to assist.
I'm afraid, route planning feature is not available in Toolset Maps. It would require a fair deal of customization that falls outside the scope of support that we provide here in the forums.
Alternatively, there are a number of third-party map plugins that can be used for maps where route planning is needed. Here are a few articles that review some of the popular options: hidden link hidden link
Thanks for the answer. Maybe you misunderstood my question. I am very satisfied with toolset maps and don't want any other tool. I only miss the option that a visitor can calculate a route to a marker from the toolset.
See pictures.
Maybe it works and I only did something wrong with the google maps api.
