# Signature [#](https://gudhub.com/docs/gh-elements/signature/#signature)

**Signature** is a gh-element that allows to sign the item or application. It provides the space where user can write his signature.

## Functional Characteristics [#](https://gudhub.com/docs/gh-elements/signature/#functional-characteristics)

This element is used to sign documents immediately in application. Use it to get digital signature.

## Value Format [#](https://gudhub.com/docs/gh-elements/signature/#value-format)

Every signature is saved in the separated file. Exactly the ID of that file is a value of the field.

Copy

```json
{
    "field_value": "941185"
}
```

## Element Options [#](https://gudhub.com/docs/gh-elements/signature/#element-options)

Signature does not have any additional options. It can be configure using only [standard field settings](https://gudhub.com/docs/understanding-gudhub/gh-elements-structure/setting-overview/).

## Element Style [#](https://gudhub.com/docs/gh-elements/signature/#element-style)

The signature as lots of other elements has a standard set of [style settings](https://gudhub.com/docs/understanding-gudhub/gh-elements-structure/setting-overview/). As for interpretation, its types are described in [the last chapter](#interpretation).

## Data Model [#](https://gudhub.com/docs/gh-elements/signature/#data-model)

The element data model is quite simple:

Copy

```json
{
    "data_model": {
        "interpretation": []
    }
}
```

| Name | Type | Description |
| :-- | :-- | :-- |
| interpretation | `array` | _contains all interpretation types and their properties_ |

## Filtration [#](https://gudhub.com/docs/gh-elements/signature/#filtration)

With [Value](https://gudhub.com/docs/core-api/filter/value/) you can filter items by whether they are signed or not.

## Interpretation [#](https://gudhub.com/docs/gh-elements/signature/#interpretation)

Almost all item interpretations allow you to enter and save the user's signature. They differ only in size.
