There are a few different ways to zoom and centralize map.
The easiest one is to drag your map if the draggable option is turned on. The same way you can zoom map with “Zoom control” as you want or if you have “Mouse wheel to zoom” option turned on with mouse scroll. Make your live preview map version as you prefer seeing it on site and just copy/paste shortcode under your map.
The second way is to insert the additional code parts into the main shortcode.
With code help you can centralize map on one of your markers or on the exact coordinates. Write this string [google_map_easy id=”your map id” map_center=”markers id” or “x coordinate/y coordinate”] in your shortcode.
[google_map_easy id="2" map_center="1" or map_center="41.902813; 12.496376"]
You can find out the id of the chosen marker in admin area under the map.
To zoom your map with shortcode you should add [zoom=”1-20″] in it.
[google_map_easy id="2" map_center="1" zoom="5"]
