Custom html attributes for HtmlInputFile

Question

I create a HtmlInputFile like this:

HtmlInputFile input = new HtmlInputFile();

Which gives me HTML output like this:

<input id="id..." name="name..." type="file">

I would like to add the "multiple" attribute to this file upload, so that I get this output:

<input id="id..." name="name..." type="file" multiple>

HtmlInputFile supports various HTML attributes, but it lacks support for multiple. Is there any way to add it?

Thank you very much!

I did use passthrough attributes in JSF pages before, but I don't know how to use them when I'm generating the elements programmatically. — Benedikt Gansinger, Jul 26 '18 at 09:23

Try:

input.getPassThroughAttributes(true).put("multiple", "true");
