+#### Other event handlers
+
+For events that don't have their own configuration functions in the `attrs` block, you can use `addEventListener` with the `name` of the event, `options`, and an pass an `eventListener` which receives a `WrappedEvent`. In this example, we're defining the behavior of a `Form` element when it triggers the `submit` event:
+
+```
+Form(attrs = {
+    this.addEventListener("submit") {
+        console.log("Hello, Submit!")
+        it.nativeEvent.preventDefault()
+    }
+})
+```
+
 Your event handlers receive wrapped events that inherit from `GenericWrappedEvent`, which also provides access to the underlying `nativeEvent` – the actual event created by JS runtime -

-There are more event listeners supported out of a box. We plan to add the documentation for them later on. In the meantime, you can find all supported event listeners in the [source code](https://github.com/JetBrains/androidx/blob/compose-web-main/compose/web/src/jsMain/kotlin/androidx/compose/web/attributes/EventsListenerBuilder.kt).
