## Example

## TODO: Redo Kotlin example with Kotlin DSL for enumerables and dropdowns

### Using an integer index

{% tabs %}
{% tab title="Java" %}

```java
@Dropdown(
    title = "My Dropdown",
    titleKey = "", // Sets the options tile translation key, default = ""
    description = "This is my dropdown", // Sets the options description, default = ""
    descriptionKey = "", // Sets the options description translation key, default = ""
    icon = "/my_dropdown.svg", // Sets the icon used for the option, default = ""
    category = "Dropdowns", // Sets the options category, default = "General"
    categoryKey = "", // Sets the categories translation key, default = ""
    subcategory = "General", // Sets the options subcategory, default = "General"
    subcategoryKey = "", // Sets the options subcategory translation key, default = ""
    options = { "HELLO", "WORLD", "ONECONFIG" }, // Recommended, default = {}
    optionsKey = { } // Allows for translating entries, default = {}
)
public static int myDropdown = 0; // 0 = "HELLO"
```

{% endtab %}

{% tab title="Kotlin" %}

```kotlin
var myDropdown: String by radiobutton(
    name = "My Dropdown",
    defaultOption = "HELLO",
    options = arrayOf("HELLO", "WORLD", "ONECONFIG"),
    nameKey = null, // Sets the options name translation key, default = null
    description = "This is my dropdown", // Sets the options description, default = null
    descriptionKey = null, // Sets the options description translation key, default = null
    icon = "/my_dropdown.svg", // Sets the icon used for the option, default = null
    category = "Dropdowns", // Sets the options category, default = "General"
    categoryKey = null, // Sets the categories translation key, default = null
    subcategory = "General", // Sets the options subcategory, default = "General"
    subcategoryKey = null, // Sets the options subcategory translation key, default = null
    optionKeys = arrayOf(), // Sets the options translation keys, order same as options, default = arrayOf()
    stringTransformer = { it.lowercase() }, // Sets how to get the name for the option, default = { it.toString() }
)
```

{% endtab %}
{% endtabs %}

### Using a custom enum class

{% tabs %}
{% tab title="Java" %}

```java
public enum MyDropdownOptions {
    HELLO,
    WORLD,
    ONECONFIG;
}

@Dropdown(
    title = "My Dropdown",
    titleKey = "", // Sets the options tile translation key, default = ""
    description = "This is my dropdown", // Sets the options description, default = ""
    descriptionKey = "", // Sets the options description translation key, default = ""
    icon = "/my_dropdown.svg", // Sets the icon used for the option, default = ""
    category = "Dropdowns", // Sets the options category, default = "General"
    categoryKey = "", // Sets the categories translation key, default = ""
    subcategory = "General", // Sets the options subcategory, default = "General"
    subcategoryKey = "", // Sets the options subcategory translation key, default = ""
    // this field cannot be present when using an enum: options = { "HELLO", "WORLD", "ONECONFIG" }, // Recommended, default = {}
    optionsKey = { } // Allows for translating entries, default = {}
)
public static MyDropdownOptions myDropdown = MyDropdownOptions.HELLO;
```

{% endtab %}

{% tab title="Kotlin" %}

```kotlin
enum class MyRadioOptions(val displayName: String) {
    HELLO("hi"),
    WORLD("world"),
    ONECONFIG("OneConfig!"),
}

var myDropdown by radiobutton(
    name = "My Dropdown",
    defaultOption = MyDropdownOptions.HELLO,
    options = MyDropdownOptions.entries.toTypedArray(),
    nameKey = null, // Sets the options name translation key, default = null
    description = "This is my dropdown", // Sets the options description, default = null
    descriptionKey = null, // Sets the options description translation key, default = null
    icon = "/my_dropdown.svg", // Sets the icon used for the option, default = null
    category = "Dropdowns", // Sets the options category, default = "General"
    categoryKey = null, // Sets the categories translation key, default = null
    subcategory = "General", // Sets the options subcategory, default = "General"
    subcategoryKey = null, // Sets the options subcategory translation key, default = null
    optionKeys = arrayOf(), // Sets the options translation keys, order same as options, default = arrayOf()
    stringTransformer = MyRadioOptions::displayName, // Sets how to get the name for the option, default = { it.toString() }
)
```

{% endtab %}
{% endtabs %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docsv1.polyfrost.org/configuration/available-options/selector-options/dropdown-option.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
