Select Remote

The io.kvision.form.select.SelectRemoteInput component, contained in kvision-select-remote module, is a special component you can use to render a select box with options loaded from the server. SelectRemoteInput is bound directly to the method of the remote service. The method signature looks like this:

import dev.kilua.rpc.annotations.RpcService
import dev.kilua.rpc.SimpleRemoteOption

@RpcService
interface IDictionaryService {
    suspend fun dictionary(state: String?): List<SimpleRemoteOption>
}

The state parameter allows you to send optional, additional data to the backend service, with the help of the stateFunction parameter of the SelectRemoteInput constructor.

The SimpleRemoteOption class is defined as:

@Serializable
data class SimpleRemoteOption(
    val value: String,
    val text: String? = null
)

and allows to send value and label for every option.

To use SelectRemote form control, you initialize it with the ServiceManager instance and a callable reference to the right method.

SelectRemote(serviceManager = getServiceManager<IDictionaryService>(), 
    function = IDictionaryService::dictionary,
    stateFunction = { someState.toString() },
    label = "Select option from the dictionary"
)
