By default, the popup opens when you hover over a marker and closes when you click the close icon, click outside the map, or hover over another marker. You can also choose to have the popup open with or without the required offset when the user clicks on the marker.

In addition to hovering or clicking, you can set the popup to open automatically when the map loads or to remain open at all times.

The plugin also provides functionality to open custom links with a simple click on the marker.

On the demo map on this page, you can see examples of different popup-opening behaviors.
