Add Data attribute to select option

[BlackBurnVP]

For now it's impossible to add some data attributes to select options. If we add it to html so it's stays under this option, but not transfers to sumoselect optWrapper

Could you give me an example of what you would need?

I think he would like the attributes set against the regular options transferring to the equivalent "li".
so when this is "converted" to a sumoselect:
{select}
{option data-whatever="test">option1{/option}
{option data-something="else">option2{/option}
{/select}

it ends up like this:
{div class="optWrapper"}
{ul class="options"}
{li class="opt selected" data-whatever="test"}{label}option1{/label}{/li}
{li class="opt" data-something="else"}{label}option2{/label}{/li}
{/ul}
{/div}

Yes. It's what I want to achieve. Thank you

I see, I will handle this as soon as I have time

[AzzaAzza69]

This would do it:
in the createLi()...

I changed:

     // AzzaAzza69 : create without any attributes (including class!)
     const li = $(`<li><label>${opt.html()}</label></li>`);

     // +AzzaAzza69 : copy all attributes from original option to new list item
     for(attr of opt[0].attributes) {
       li[0].setAttribute(attr.name, attr.value);
     }
     li[0].classList.add('opt');
...
// -AzzaAzza69 : new attribute copy will pull these across
//          if (opt.attr('class'))
//            li.addClass(opt.attr('class'));

//          if (opt.attr('title'))
//            li.attr('title', opt.attr('title'));
...
