```kotlin
@ExperimentalMaterial3AdaptiveApi
object ListDetailPaneScaffoldRole
```
The set of the available pane roles of [ListDetailPaneScaffold](/jetpack-compose/androidx.compose.material3/material3-adaptive/components/ListDetailPaneScaffold). Basically those values are
aliases of [ThreePaneScaffoldRole](/jetpack-compose/androidx.compose.material3/material3-adaptive/classes/ThreePaneScaffoldRole). We suggest you to use the values defined here instead of
the raw [ThreePaneScaffoldRole](/jetpack-compose/androidx.compose.material3/material3-adaptive/classes/ThreePaneScaffoldRole) under the context of [ListDetailPaneScaffold](/jetpack-compose/androidx.compose.material3/material3-adaptive/components/ListDetailPaneScaffold) for better
code clarity.
