# Using The Datagrid
Using the Datagrid on a mobile device is similar to but not the same as [on a computer](/concepts-and-fundamentals/on-a-computer/using-the-datagrid.md).
## Register Menu
Only modules and registers you have access to with your event and duty will appear in the menu.
Modules have a light blue background and Registers have a white background.
To access the records within a register, touch the respective menu item.
Registers appear within module sections of the main menu
In tablet mode the Activity Log (Recent Activity) will be listed in the middle of the screen and counters to the right grouped by category.
### Register Views
Registers work differently to on a computer. You must first choose a filter/counter to activate Register mode.
### Filter Screen
The Filter Screen is used to ensure that the register is opened with filtered data.
Each register has a selection of filter menus displayed in bold. These are typically collapsed and must be expanded to access a specific filter.
#### Expanding and Collapsing Filter Menus
To access them expand them using the right arrow icon. Expanded filter menus appear with a down arrow icon, to collapse them and allow more screen for other sections, tap the down icon.

Some filters have counters to show you the total number of items.
#### Showing Hidden Filters
Others may be hidden. These will have an eye icon along with a total items.
To reveal all hidden filters, simply tap on this.
#### Activating Filters
To activate a filter and launch [Register Mode](#register-mode), tap the respective row on your device.
### Register Mode
Choosing a register from the main screen activates Register Mode. This is the default mode and you can switch back to it from other views (such as [Map Mode](#using-the-map-mode) using the Datagrid icon ).
This is different to working on a computer in that there is no grid view. Items are instead listed vertically based on the screen size.
Selecting items will activate the Bulk Actions menu in a bar at the top of the screen. This includes [Offline Store](/concepts-and-fundamentals/mobile-app/working-offline.md#access-1) options).

### Map Mode
Map Mode can be activated from registers that support it using the Map button which has a pin icon. The pin icon also contains a total number of records with locations in the current filter which can be viewed on the map.
Map mode fills the entire mobile screen and from this screen you can also:
* Zoom into your current location
* Show different layers and mapping views (from the bottom right corner)\
* Select records individually to view and edit
When zoomed out, multiple records are indicated in blue with a number indicating how many records are in that same area. You will see them as individual records as you zoom in closer to them.
