How to implement selecting multiple buttons at once using angularjs?

Question

JavaScript

Here is the site address in the section "Vyberte číslo linky" (where there are numbers) you can choose only one bus, tram or trolleybus number. Can you please tell me how to implement the selection of several numbers at once and their display on the map?
