+# Basic url drilldown implementation
+
+Url drilldown allows navigating to external URL or to internal kibana URL.
+By using variables in url template result url can be dynamic and depend on user's interaction.
+
+URL drilldown has 3 sources for variables:
+
+- Global static variables like, for example, `kibanaUrl`. Such variables won’t change depending on a place where url drilldown is used.
+- Context variables are dynamic and different depending on where drilldown is created and used.
+- Event variables depend on a trigger context. These variables are dynamically extracted from the action context when drilldown is executed.
+
+Difference between `event` and `context` variables, is that real `context` variables are available during drilldown creation (e.g. embeddable panel),
+but `event` variables mapped from trigger context. Since there is no trigger context during drilldown creation, we have to provide some _mock_ variables for validating and previewing the URL.
+
+In current implementation url drilldown has to be used inside the embeddable and with `ValueClickTrigger` or `RangeSelectTrigger`.
+
+- `context` variables extracted from `embeddable`
+- `event` variables extracted from `trigger` context
+
+In future this basic url drilldown implementation would allow injecting more variables into `context` (e.g. `dashboard` app specific variables) and would allow providing support for new trigger types from outside.
+This extensibility improvements are tracked here: https://github.com/elastic/kibana/issues/55324
+
+In case a solution app has a use case for url drilldown that has to be different from current basic implementation and
+just extending variables list is not enough, then recommendation is to create own custom url drilldown and reuse building blocks from `ui_actions_enhanced`.
