Can I use html5 data attribute in HTML select box element?

Question

Any idea can I use .data attribute in HTML select box?I red HTML5 documents but I didn't find any information that could help me.

Is it legal:

<span>Select depatament</span>
<span>
    <select id="department" onchange="EnableSelectBox(this)" data-spacing="10cm">
        <option selected disabled>-Select-</option>
    </select>
</span>

Yes, it is perfectly fine. But, onchange="EnableSelectBox(this)" isn't that pretty! More Info — lshettyl

You can use data-attributes pretty much everywhere. You can also use self-made custom attributes pretty much everywhere (but try choosing names that won't be introduced later by the W3C specs, or you'll need to fix your code). — Andrea Ligios

Every HTML element may have any number of custom data attributes specified, with any value — Andy

Yes it fine to use data in Html5 tag. I don't know why you want to use in such a way, but you can use it.

for example like this

$(document).ready(function() { alert($('#department').data('spacing')); });

Using data attributes

Any attribute on any element whose attribute name starts with data- is a data attribute.

To answer the question: Yes. You can use data attributes on any element.

It works fine. Test in JS using:

alert(document.getElementById("department").getAttribute("data-spacing"))
