formAttributes property

dynamic formAttributes
getter/setter pair

Highcharts v11.2.0 and older. An object containing additional key value data for the POST form that sends the SVG to the export server. For example, a target can be set to make sure the generated image is received in another frame, or a custom enctype or encoding can be set.

With Highcharts v11.3.0, the fetch API replaced the old HTML form. To modify the request, now use fetchOptions instead.
