Quando la funzionalità di trascinamento è attivata, gli utenti possono trascinare i marcatori sulla mappa utilizzando il mouse
o i tasti freccia. Per rendere trascinabile un indicatore, imposta la proprietà AdvancedMarkerElement.gmpDraggable
su true.
La seguente mappa di esempio mostra un indicatore trascinabile che visualizza la sua posizione aggiornata
al termine del trascinamento (viene attivato l'evento dragend):
Per trascinare un indicatore con la tastiera:
Premi il tasto Tab finché non viene selezionato il marcatore.
Utilizza il tasto Freccia per spostarti sul marcatore desiderato.
Per attivare il trascinamento, premi Opzione + Barra spaziatrice o Opzione + Invio (Mac), Alt + Barra spaziatrice
o Alt + Invio (Windows).
Utilizza i tasti Freccia per spostare il marcatore.
Per rilasciare l'indicatore nella nuova posizione, premi la barra spaziatrice o Invio. In questo modo
verrà disattivato anche il trascinamento.
Per disattivare il trascinamento e riportare il marcatore nella posizione precedente, premi
Esc.
Per impostare un testo descrittivo per un indicatore, che può essere letto dagli screen reader, utilizza
l'attributo AdvancedMarkerElement.title, come mostrato di seguito:
