jQuery - select element by any data-attribute

Question

Appreciate if you help me. I have code which hide and show elements with specific data-attribute, ie

I have couple of tag-lists

<div class="row no-width-margin" id="selector-theme">
   <h5 class="tag-title">Tag group 1</h5>
      <ul class="tag-list">
         <li class="tag-list-item" data-theme="all-theme">All themes</li>
         <li class="tag-list-item" data-theme="holidays-theme">Holidays</li>
         <li class="tag-list-item" data-theme="spring-theme">Spring</li>
         <li class="tag-list-item" data-theme="new-year-theme">New year</li>
      </ul>
</div>
<div class="row no-width-margin" id="selector-sector">
   <h5 class="tag-title">Tag group 2</h5>
   <ul class="tag-list" style="padding: 0">
      <li class="tag-list-item" data-sector="all-sector">All sectors</li>
      <li class="tag-list-item" data-sector="cinema-sector">Movies</li>
      <li class="tag-list-item" data-sector="entertainment-sector">Entertainment</li>
   </ul>
</div>

and I have dozens of elements like this

<div class="file-box" data-theme="all-theme,holidays-theme" data-sector="all-sector,cinema-sector">
  <div class="file">
    <div class="image">
    </div>
    <div class="file-name">
    </div>
  </div>
</div>

and, of course, jQuery

$('.tag-list-item').click(function () {
                $(this).parent().find('.tag-list-item').each(function (i, elem) {
                    console.log(elem);
                    $(elem).removeClass('tag-list-chosen');
                });
                var param = $(this).data('theme').toString();
                $(this).addClass('tag-list-chosen');
                $('.file-box').each(function (i, elem) {
                    var params = $(this).data('theme').split(',');
                    if (params.indexOf(param.toString()) == -1) {
                        $(elem).fadeOut('slow');
                    } else {
                        $(elem).fadeIn('slow');
                    }
                });
            });

The problem is, I can select element by only one attribute (data-theme) via tag list . How can I change it to data-ANY (or something like this), to make my code more universal?

why not store all data tags in a variable and loop them?

 $('.tag-list-item').click(function() { $(this).parent().find('.tag-list-item').each(function(i, elem) { $(elem).removeClass('tag-list-chosen'); }); if ($.hasData(this)) { var datas = $(this).data(); var param; for (var key in datas) { param = datas[key]; } } $(this).addClass('tag-list-chosen'); $('.file-box').each(function(i, elem) { var params = $(this).data('theme').split(','); if (params.indexOf(param.toString()) == -1) { $(elem).fadeOut('slow'); } else { $(elem).fadeIn('slow'); } }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="row no-width-margin" id="selector-theme"> <h5 class="tag-title">Tag group 1</h5> <ul class="tag-list"> <li class="tag-list-item" data-theme="all-theme">All themes</li> <li class="tag-list-item" data-theme="holidays-theme">Holidays</li> <li class="tag-list-item" data-theme="spring-theme">Spring</li> <li class="tag-list-item" data-theme="new-year-theme">New year</li> </ul> </div> <div class="row no-width-margin" id="selector-sector"> <h5 class="tag-title">Tag group 2</h5> <ul class="tag-list" style="padding: 0"> <li class="tag-list-item" data-sector="all-sector">All sectors</li> <li class="tag-list-item" data-sector="cinema-sector">Movies</li> <li class="tag-list-item" data-sector="entertainment-sector">Entertainment</li> </ul> </div> <div class="file-box" data-theme="all-theme,holidays-theme" data-sector="all-sector,cinema-sector"> <div class="file"> <div class="image"> image </div> <div class="file-name"> filename </div> </div> </div> 

Hope it functions on the way you wanted it to be.
