# POS layout

> Organize your items into screens and tiles in the backoffice: it's exactly the grid your staff will see on the register.

The grid of buttons your staff taps on the register is built here, in the backoffice. This is where you decide which items appear, on which screen, in what order, and at what tile size. This page applies to both modes — only the labels differ: in restaurant mode, the editor is called **Menus & screens** (titled **Menu Builder**) in the **Menu & Catalog** section; in retail mode, it's called **POS layout** in the **Catalog** section. For the difference between the two modes, see [modes](/en/modes).

## The idea: screens and tiles

Two concepts are all you need:

* A **screen** is a page on the register. Every location has a home screen (**Home screen**), and you can create subscreens — for example "Hot drinks" or "Desserts".
* A **tile** is a button placed on a screen. There are two kinds:
  * an **item tile** (**Item tile**, **Product tile** in retail mode): tapping the tile on the register adds the item to the order;
  * a **category tile** (**Category tile**): tapping the tile opens another screen.

Screens nest up to **three levels at most** (home plus two levels of subscreens), so your staff can reach any item in two taps or fewer.

<Note>
  An item created in the catalog only shows up on the register once it's placed
  as a tile on a screen reachable from home. The **On menu** column in the item
  library flags the ones still waiting to be placed — see [menu and
  items](/en/backoffice/menu).
</Note>

## The three-pane editor

* **On the left, Screens**: the tree of your screens, each with its tile count. Click a screen to open it in the center.
* **In the center, the preview** (**POS preview**): a faithful reproduction of the screen as it will appear on the register, with its four-column grid. A breadcrumb above lets you move back up from screen to screen. Click a tile to adjust it, double-click a category tile to enter its screen.
* **On the right, Library**: the library you add tiles from. When a tile is selected, this panel becomes the tile inspector.

## Multiple menus

A location can have several menus — for example a **Lunch** menu and a **Dinner** menu. Each menu has its own screens and its own tiles; they are completely independent. On the register, your staff shows one menu at a time and switches between them with a tap, see [taking orders](/en/pos/taking-orders).

The **Menus** bar at the top of the editor lists your menus. The selected menu is highlighted; everything below it — the tree, the preview, the library — belongs to that menu.

* **Switch menu**: click its name in the bar.
* **Add a menu**: the **+ Menu** button creates a new menu with an empty home screen, then opens it. Give it its name next.
* **Rename a menu**: open it, then click its name or the pencil above the preview. The field enters **Editing** mode and selects the current name. Type the new name, then confirm with the checkmark or Enter; Escape cancels the edit.

<Warning>
  Deleting a menu (**Delete menu** in its settings) deletes all its screens and
  all their tiles. A location must keep at least one menu: the last one cannot
  be deleted.
</Warning>

## Adding tiles to a screen

<Steps>
  <Step title="Open the screen to fill">
    Select it in the **Screens** tree or navigate through the preview.
  </Step>

  <Step title="Pick from the Library">
    The right panel offers two tabs: **Items** (**Products** in retail mode) for
    items, and **Screens** for screens. The **Search library…** bar filters by
    name.
  </Step>

  <Step title="Click an item or a screen">
    It's added at the end of the grid. An **Already on this screen** checkmark
    flags items already placed on the open screen.
  </Step>
</Steps>

<Note>
  The name shown on a tile is always the name of the item or screen it points
  to. To rename a tile, rename the item in the catalog or the screen in its
  settings.
</Note>

## Creating subscreens

Two paths lead to the same result:

* the **Add subscreen** button on the open screen's settings card;
* the **New subscreen** button in the Library's **Screens** tab.

The new screen is created under the open screen, and a category tile is automatically placed on the parent screen so it's reachable right away. Then give it its real name in the **Name** field of the settings card; the **Nested under …** hint reminds you of its parent screen. You can also give it a color with the **Color** picker.

Beyond three levels, the button is disabled and a **Maximum depth reached** message appears.

<Warning>
  Deleting a screen (trash icon on its settings card) also deletes all its
  subscreens and all their tiles. The home screen cannot be deleted.
</Warning>

## Adjusting a tile

Click a tile in the preview: the right panel becomes its inspector.

* **Width**: the tile's width, from **1 col** to **4 cols**. The register grid has four columns, so a 4-column tile spans the full width — handy for showcasing your best sellers.
* **Position**: the **Up** and **Down** buttons move the tile within the grid.
* **Open this screen** (category tile): opens the target screen in the editor.
* **Open in catalog** (item tile): opens the item library to edit the item itself.
* **Remove tile**: removes the tile from the screen. The item or screen it points to is not deleted — only the tile goes away.

## Colors

Every screen can take a color (**Color** picker in its settings), and so can every item (**Color** field in the item editor). On the register, every tile shows its own color only: a tile without a color stays on the neutral surface, even when its screen is colored. Coloring a screen only tints its category tile, not the items inside it.

## What your staff sees on the register

On the register, the screen reproduces your preview exactly: the same four-column grid, the same tiles, in the same order.

* Item tiles show the name and price. Tapping them adds the item to the current order — see [taking orders](/en/pos/taking-orders).
* Category tiles open their screen; a back arrow at the top takes you back up.
* A screen with no tiles shows "No buttons on this screen yet. Add some in the back office."

## Publishing to the registers

Your changes save automatically to a draft (a **Saving draft…** badge shows
while saving), but the registers see none of it until you click **Publish all
changes** in the global header. The location's saved catalog, tax, receipt, and
settings changes are published together as one block. The confirmation dialog
and required refresh on the main register are covered in [menu and
items](/en/backoffice/menu).
