We’ve made a couple improvements to the built-in Map element to make it easier to build UIs that involve selecting an item on a map.
If the map is displaying a list of markers, you can now use a new action, “Set current map marker”, to change the map’s current marker. Previously, the only way to change which marker was selected for the user to click on it; you can now change it via a workflow action.
We’ve also added a way to make it visible to the user which marker is currently selected. There’s now a “Custom selected icon” property that lets you specify an icon to show for the selected marker, so that you can visually distinguish the marker the user clicked on, or that you selected via the new action. The options for “Custom selected icon” are similar to those for “Customized icon”: you can either upload an image directly, or select a field on the data you are displaying to pull a selected icon from.
