## Features

- Dynamic UI generation based on JSON schema

- Multi-language support (English, Finnish, Swedish)

- Support for various input types (select, number, string, textarea)

- Nested object and array handling

- Real-time UI updates on language change

## File Structure

- `fct_parser.R`: Contains functions for parsing the JSON schema

- `fct_ui.R`: Contains functions for creating UI elements

- `app_ui.R`: Defines the main UI structure of the Shiny app

- `app_server.R`: Defines the server-side logic of the Shiny app

## Key Functions
