+Поведение браузера при нажатии на сервис.
+С помощью этого свойства, можно сделать открытие сервиса в текущем или новом окне.
+
+```yaml
+behaviour:
+  target: _blank
+```
+
+Values:
+
+| Value     | Description                                                                                                                     |
+|-----------|---------------------------------------------------------------------------------------------------------------------------------|
+| `_blank`  | Usually a new tab, but users can configure browsers to open a new window instead                                                |
+| `_self`   | The current browsing context                                                                                                    |
+| `_parent` | The parent browsing context of the current one. If no parent, behaves as `_self`                                                |
+| `_top`    | The topmost browsing context (the "highest" context that's an ancestor of the current one). If no ancestors, behaves as `_self` |
+
+Default: `_blank`
