Default Value: false

If you need to switch the display of this DevExtreme component to right-to-left, enable a specifically designed configuration option - rtlEnabled. When this option is set to true, the text flows from right to left, and the layout the component's elements is reversed. To switch the entire application/site to a right-to-left representation, use the static DevExpress.rtlEnabled field.

type

visible

A Boolean value specifying whether or not the widget is visible.

Type: Boolean
Default Value: true

width

Specifies the width of the widget.

Type: Number|String| function

  • function - the function returning the widget width (e.g., width:function(){ return baseWidth - 10 + "%"; })

zoom

The zoom level of the map.

Type: Number
Default Value: 1

By default, the widget sets the automatically calculated zoom value each time a marker or a route is added to the map. In this case, zoom is set to the maximum value, allowing all markers and routes to be displayed at the same time. Set the autoAdjust option to false to disable this behavior.

Note that if the autoAdjust option is set to true, the zoom level can only be decreased to display all markers and routes. If the current zoom level and center position allow all routes and markers to be displayed on the map, they remain unchanged.

Knockout
