Using :data attribute as a selector to filter elements

Question

I am trying to use a custom data attribute to filter things via dropdown selections. I can't seem to get the selector to work correctly, and was just wondering if that is actually possible. Currently looking at https://api.jqueryui.com/data-selector/ but I can't seem to get it to work. My HTML: ```

Clothes
Add to Cart

Jewelry

Accepted Answer

Just use the selects value directly to target the elements with the correct data attribute

```
$(document).ready(function () {
    $('#item-filter-select').on('change', function () {
        if (this.value == 'all') {
            $('.item').show();
        }else{
            var elems = $('.item[data-type="'+this.value+'"]');
            $('.item').not(elems).hide();
            elems.show();
        }
    });
});
```

FIDDLE

or a shorter version of the above

```
$(document).ready(function () {
    $('#item-filter-select').on('change', function () {
        var elems = this.value == 'all' ? $('.item') : $('.item[data-type="'+this.value+'"]');
        $('.item').not(elems.show()).hide();
    });
});
```
