# Attribute Fields

![](/files/-Ll4oImsVCn0RN_1bsFC)

## Attribute Types

Attribute fields can be added to point, line, and polygon feature classes. The following attribute fields are available when creating/editing a feature class:

**Description**\
Allows you to input standard text.

**Date & Time** \
Presents a picker view for entering and editing the date and time. This attribute is automatically set to the current date and time when a feature is added to the map, but can easily be edited. 

**Photos**\
Allows you to attach multiple photos with the built-in camera or from the camera roll. You can also use the Markup tool to draw annotations on your photos. 

**Number**\
Allows you to enter a decimal or floating point number. *Tip: it is helpful to put the units in the attribute name.*

**List of Values**\
Present a selection of values, for example {True,False} or {Sand,Gravel,Dirt}. You can enable multi select if it's necessary to select more than one value during data collection. Note: when creating a new 'list of values' attribute you can copy a list from an existing feature class or import the options from a text, CSV, or JSON file. 

**Address**\
Allows you to enter a standardized street address. *Note: if you need to enter an address in a non-standard format it may be better to use the Description attribute type.* 

**Website** \
Allows you to enter a web URL. When a URL is present you can access it by tapping on it. 

**Telephone**\
Allows you to enter a standard phone number. When a number is present you can tap it to be presented with the option to call that number.

**Checkbox**\
A checkbox can be toggled on and off.

**Auto-Incrementing ID**\
Automatically assigns incremental IDs as features are added to the map. IDs increment globally, accross all projects to avoid reusing the same ID. You can manage the format of Auto-Incrementing IDs in the Settings App. 

**Barcode**\
Allows you to utilize a camera-based barcode scanner to populate a field with barcode data. *Feature available as of version 1.0.7.*

**Rotation**\
Define an angle of rotation for a feature. *Note: for point features you can choose to display the 'pin' icon at the entered angle.* 

{% hint style="info" %}
Tip: You can add multiple instances of an attribute type to a feature class. 
{% endhint %}

{% hint style="warning" %}
Note: Description is the only standard attribute allowed in KML. When exporting to KML all non-description fields will be formatted as an HTML table and inserted into the Description attribute.
{% endhint %}
