Specify the Yandex.Maps API key and select the API type paid or free. The current data source (v.1.0.0, v.2.0.0) is standard Joomla articles.
The coordinate field
The module needs to know where to get the coordinate values for the placemarks on the map from. To specify coordinates in Joomla articles use custom fields. Create a custom field for aticles. Then select the created field from the drop-down list in module settings.
Option 1. Standard Joomla text field for specifying coordinates
Either a standard text type field is suitable. In this case, it is necessary to specify the coordinates in it in the form of decimal fractions separated by commas. The coordinates will be filled in manually by you.
Option 2. Using the plugin Fields - WT Yandex Map

Select one or more categories whose articles have a field with coordinates and should be displayed on the map. If necessary, specify the tags for filtering. Limit the number of articles displayed on the map.
Parameters "The fields of the marker layout articles (comma-separated enumeration)" and "The fields of the articles for the popup window layout (comma-separated)" indicate which articles data is available when creating your own marker and popup window content layouts. As part of the quick start, it is recommended to leave these parameters by default.
The parameter "Process content with plugins" includes the processing of texts of Joomla articles with plugins: short codes in the text will be replaced with their contents.
Tab "Display"

Pop-up windows on clicking on a placemark are disabled by default.
