 - No `inline` prop property, including a single action display;

+#### Manually providing semantic menu information
+Due to limitations of Vue, when using a custom wrapper for action components, you have to provide the semantic menu type yourself.
+This is used for keyboard navigation and accessibility.
+In this example a `NcActionInput` component is used within a custom wrapper, so `NcActions` is not able to detect the semantic menu type of 'dialog' automatically,
+meaning it must be provided manually:
+
+```vue
+<template>
+	<NcActions menu-semantic-type="dialog">
+		<MyWrapper />
+	</NcActions>
+</template>
+<script>
+import Pencil from 'vue-material-design-icons/Pencil.vue'
+
+export default {
+	components: {
+		MyWrapper: {
+			template: `
+<NcActionInput trailing-button-label="Submit" label="Rename group">
+	<template #icon>
+		<Pencil :size="20" />
+	</template>
+</NcActionInput>`,
+		},
+		components: {
+			Pencil,
+		},
+	},
+}
+</script>
+```
