Features of the New UI Designer:

Dynamic Field Addition: Users can dynamically add fields with custom types (Textbox, Number, Dropdown, Slider, Checkbox) and set appropriate attributes such as labels, placeholders, min/max values, and dropdown options.

Visibility Control: Depending on the selected field type, only the relevant attributes are shown (e.g., placeholders for Textboxes, min/max values for Number/Slider fields, and choices for Dropdowns).

Preview Added Fields: The gr.JSON component allows the user to preview all the fields they have added in JSON format, making it easier to review the design.

Code Generation: Once all fields are added, users can generate the Gradio code, which includes the corresponding input components and a basic function that processes user inputs.

Example Workflow:
Select a component type (e.g., Textbox) and specify a label like "Name". Optionally set a placeholder (e.g., "Enter your name").
Add another component type (e.g., Slider) and set labels and min/max values.
Add as many fields as required, and the list of added components will be shown.
Finally, click the "Generate Code" button to generate the Python code for your Gradio interface.
