In the Pro version you can control the content of the tooltip using templates.

In the Tooltip section you can set a global template and on each data type (Regions and Markers) it’s possible to override that template.

You can use placeholders in the template that will be replaced with the content of that property. This is particularly useful if you’re using external data sources, since you’ll have more fields to populate the tooltip.

Each placeholder should be wrapped in curly brackets and it should be the property name. Example:

{title} and {tooltipContent} exist by default in your data entry. Other placeholders can be used according to your data source.

You can use HTML code to enhance the content.

In the settings page of the plugin, in the Editing tab you can also change the field type for the tooltip template to be a text area or a rich text editor, to have more freedom to create your tooltip template.
