Web browser warnings of "A form element should have an id or name attribute"

[Jonathanliu92251]

When Multiselect generates html code, form elements may miss something, which cause warnings from web browser.
a quick example is, when open official website with debug mode "https://davidstutz.github.io/bootstrap-multiselect/#configuration-options-onChange", you can see browser 100+ warnings (Snapshot as below):
"A form element should have an id or name attribute" and "No label associated with a form field"

It's better to fix these warnings, thanks a lot.

In case anyone else ends up here, I was able to resolve these accessibility findings reported from multiple accessibility checkers (Chrome Lighthouse, Axe DevTools, WAVE, etc) using the following:

    $('#myMultiSelect').multiselect({
        buttonTitle: function (options, select) {
            //ensures the title on the button is not redundant with the text displayed to avoid redundant title findings when selecting one item
            return 'Select Location(s)'
        },
        //button template addresses bootstrap 5 incompatibilities with bootstrap-multiselect: https://github.com/davidstutz/bootstrap-multiselect/issues/1230
        //option template converts buttons to divs to avoid nested interactive controls findings
        templates: {
            option: '<div class="multiselect-option dropdown-item"></div>',
            button: '<button type="button" class="multiselect dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false"><span class="multiselect-selected-text"></span><b class="caret"></b></button>',
        }, 
    });

    $('.multiselect-container div').each(function (index) {
       //adapted from response found in Stack Overflow: https://stackoverflow.com/questions/41068832/awesome-bootstrap-checkboxes-for-bootstrap-multiselect#answer-41070906
        var id = 'multiselect-' + index,
            $input = $(this).find('input');

        // Associate the label and the input
        $(this).find('label').attr('for', id);
        $input.attr('id', id);

        //remove redundant titles
        $(this).removeAttr('title');
    });

Hope that helps and good luck!
