This is rude. And please speak in English, this is a website in English.
The plugin’s description and the screenshots show exactly which are the possible options/parameters.
Also, the map is not fixed. It’s responsive (of course, when used with a correct responsive theme)….
The map always has 100% width of the parent container’s width. And you can specify the height via the shortcode. So it’s not fixed.
The 100% width, sometimes does not work with a free/poorly coded theme which claims to be responsive but it isn’t.
To convince yourself, try the plugin with the Twenty Sixteen theme, which is correctly coded by the WordPress team. And you’ll see that the map isn’t “fixed”.
