## Integration with Other Features

When the Grid is in `Stacked` data layout mode, it does not render column headers. As a result, column features like sorting, filtering, grouping, locking are not available through the classic Grid UI. Instead, use [ToolBar command tools](slug:components/grid/features/toolbar#command-tools) to enable the same functionality through different UI.
In `Stacked` data layout mode the Grid rendering is different and some features use different UI and UX:

Hierarchy relies on an expand/collapse button, which is below the stacked table row content.
* The Grid does not render column headers. Column features like sorting, filtering, grouping, and locking require [ToolBar command tools](slug:components/grid/features/toolbar#command-tools).
* The Grid does not render a command column. Combine [Grid row selection](slug:grid-selection-row) with [Toolbar command tools for the `Delete`, `Edit`, `Save`, and `Cancel` command buttons](slug:components/grid/features/toolbar#command-tools).
* Hierarchy relies on an expand/collapse button, which renders below the stacked table row content.

## Example

The following sample shows how to:

* Enable and disable column stacking, depending on the viewport width.
* Display 1 or 2 stacked columns, depending on the viewport width.
* Render ToolBar tools for column operations only when the Grid is in `Stacked` data layout mode.
* Render ToolBar tools for column and edit operations only when the Grid is in `Stacked` data layout mode.
