- Tags: Deprecated, Capabilities: UI

**Deprecated:**

Creates a selection group where gamepad GUI navigation will only consider selectable objects that are within the group.

### AddSelectionTuple

```luau

```

- Tags: Deprecated, Capabilities: UI

**Deprecated:**

**AddSelectionTuple** works similarly to [`GuiService:AddSelectionParent()`](https://rapi.sleaze.dev/classes/GuiService.md), but you can give it a tuple of [`GuiObject`](https://rapi.sleaze.dev/classes/GuiObject.md) that you want to be contained in the group. Beware that the second argument is *not* a table, but rather the first of several [`GuiObject`](https://rapi.sleaze.dev/classes/GuiObject.md) in the tuple. To pass the contents of a table, use `unpack`/`unpack`:

```luau
local frame = script.Parent -- Passing various GuiObject individually GuiService:AddSelectionTuple("InventoryButtons", frame.Sort, frame.Trash, frame.Drop) -- Unpacking a table of GuiObject (unpack/table.unpack are equivalent) local inventoryButtons = { frame.Sort, frame.Trash, frame.Drop } GuiService:AddSelectionTuple("InventoryButtons", unpack(inventoryButtons))
```

Parameters:

- `selectionName`: The name of the added selection.
- `selections`: The selection(s) added.

### GetErrorMessage
