# apex:mapInfoWindow

Defines an info window for the marker displayed at a location on an `<apex:map>`. The body of the `<apex:mapInfoWindow>` component is displayed in the info window when users click or tap the marker. The body of the `<apex:mapInfoWindow>` can be Visualforce markup, HTML and CSS, or even plain text.

By default only one info window displays at a time. That is, when you click another marker, the first info window disappears and the new info window appears. To display multiple info windows at once, set `showOnlyActiveInfoWindow` to `false` on the containing `<apex:map>` component.

**Note:** This component must be enclosed within an `<apex:mapMarker>` component.
