To place a Google Map on a Page or a Post use the shortcode: [[bpmap]]
You can control the height and width of the map by putting it inside a div where the height and width are designated. Change from Visual view to Text view and create your div and add the shortcode.
<div style=”height: 600px; width: 600px”> [[bpmap]]</div>
You can choose to show only markers from Posts with a specific tag:
where “categoryslug” is the (surprise) slug for the category. Make sure you are using the slug and not the category name as seen below.
