MapPopup

A standalone popup anchored to a geographic coordinate, independent of any marker. Toggle visibility programmatically via IsOpen and bind to IsOpenChanged to react when the user closes it.

Satellite package. MapPopup lives in Lumeo.Maps — install it alongside the core Lumeo package. Place it inside a <Map> ChildContent slot. For marker-attached popups use the Popup slot on MapMarker instead.

When to Use

Showing rich contextual information at a specific lat/lon without a visible marker
Displaying a location info panel triggered by an external button or list item
Pinning a persistent info card to a geographic coordinate (e.g., a selected search result)
Building custom "click-anywhere" detail panels on top of the map

API Reference

Prop	Type	Default	Description
Lat	double	0	Latitude of the popup anchor point in decimal degrees.
Lon	double	0	Longitude of the popup anchor point in decimal degrees.
IsOpen	bool	false	Whether the popup is currently visible. Use `@bind-IsOpen` for two-way binding so the popup updates your state when closed by the user.
IsOpenChanged	EventCallback<bool>	—	Fires with `false` when the user closes the popup (close button or map click). Enables two-way binding via `@bind-IsOpen`.
CloseButton	bool	true	Show a close (×) button in the popup header. Set to `false` for persistent popups controlled entirely from code.
CloseOnClick	bool	true	Close the popup when the user clicks on the map background. Set to `false` for pinned popups that should stay open until explicitly dismissed.
Html	string?	null	HTML string for the popup body. Overrides `ChildContent` when set.
ChildContent	RenderFragment?	null	Rich Blazor render fragment for the popup body. Rendered into a hidden host element; MapLibre reads its `innerHTML` when the popup opens.
