[html-formfu] set multiple values to hidden element?

[Carl Franks]

Hi,

A hidden field won't support multiple values, so you'd need to
serialize them yourself - for example with JSON.
    $field->default( encode_json( $value ) );

I'd recommend though, just using Block elements, as it's very easy to
attach IDs or class-names, which your JavaScript can target to
show/hide the blocks.
