# Field attributes

### DataObjectDropdown

<div align="left"><figure><img src="/files/LEalrOwHBCDCBEeN8A2R" alt=""><figcaption></figcaption></figure></div>

Enables a useful dropdown field with additional features such as unassign, create new and find DataObject. When using this attribute outside of a DataObject - like in a MonoBehaviour, it is necessary to add a reference to the DataLibrary object and pass the name of the DataLibrary field.

* dataLibraryFieldName: the name of the data library field
* includeSubtypes: if true, dropdown also shows derived types
* tooltip: set an additional etooltip

```csharp
public class Enemy : MonoBehaviour
{
    public DataLibrary data;
    
    [DataObjectDropdown("data")]
    public EnemyData enemyData;
}
```

### ExposeToInspector

<figure><img src="/files/0fNhlEeTp2walE4TJefV" alt=""><figcaption></figcaption></figure>

Use the ExposeToInspector attribute to mark fields which should be displayed in the popup inspector on the DataObjectDropdown property drawer.

```csharp
public EnemyData : DataObject
{
       [ExposeToInspector]
       public int health;
       [ExposeToInspector]
       public int speed;
       [ExposeToInspector]
       public GameObject prefab
       
       public Vector3 position;
}
```

### DatabrainSerialize

Mark fields which should be serialized by Databrain to a file with the \[DatabrainSerialize] attribute. Only fields of DataObjects which are in the runtime-DataLibrary will be serialized.

<pre class="language-csharp"><code class="lang-csharp"><strong>[DataObjectAddToRuntimeLibrary]
</strong><strong>public EnemyData : DataObject
</strong>{
       [ExposeToInspector]
       [DatabrainSerialize]
       public int health;
       [ExposeToInspector]
       [DatabrainSerialize]
       public int speed;
       [ExposeToInspector]
       public GameObject prefab
       
       [DatabrainSerialize]
       public Vector3 position;
}
</code></pre>

[Dropdown("dropdownIntOptions")]
public int dropdownNumber;
```

### Foldout

Group fields by foldouts (only works in the Databrain editor)

[Foldout("curves")]
public AnimationCurve curve1;
[Foldout("curves")]
public AnimationCurve curve2;

[Foldout("Numbers")]
