javascript - Convert dropdowns to radio buttons wo modifying HTML

So this is sort of an exceptional case situation - I have a plugin that I can't modify for contractual reasons. It displays a set of drop downs and I need it to display a set of radio buttons instead. Is there a js/jquery method for converting dropdowns to radio buttons w/o changing the HTML. Remember, I can add stuff - I just can modify the plugin (and thus the HTML) directly.

I get that this is a bad way to do it, trust me I don't like it any more than you do.

Possibly by detecting the values of the drop-down options and then reformatting them as radio buttons, hiding the original dropdown?

1 Can you hide the dropdown through css? – BrunoLM Commented Oct 20, 2010 at 2:07
Yeah, there are plenty of ids/selectors to work with so hiding via css should be no problem. – Thomas Commented Oct 20, 2010 at 2:08
1 It is possible through JavaScript, provide us with a snippet of the HTML... – Alex Commented Oct 20, 2010 at 2:09
There is an easier way to do this by using just Shopp code shopplugin.net/workshopp/product-variations-as-radio-inputs – RST Commented May 26, 2015 at 13:07

Sorted by: Reset to default 12

Hide the dropdown and place the new radio elements outside the form, they don't need to post, just update the dropdown value.

Here is a code example on jsFiddle.

$("#d option").each(function(i, e) { // get the options
    $("<input type='radio' name='r' />") // create a radio element
        .attr("value", $(this).val()) // set the value
        .attr("checked", i == 0) // check the first by default
        .click(function () { // add event click which updates the dropdown
            $("#d").val($(this).val()); // update the dropdown if clicked
        })
        .appendTo("#r"); // append to some visible place
});

To encapsulate this into a declarative attribute, I extended @BrunoLM 's function to style all <select>'s with a given CSS class into the radio button look.

HTML

<select class="radioSelect" id="sizeOptions">
    <option value="S">S</option>
    <option value="M">M</option>
    <option value="L">L</option>
    <option value="XL">XL</option>
    <option value="2XL">2XL</option>
    <option value="3XL">3XL</option>
    <option value="4XL">4XL</option>
    <option value="5XL">5XL</option>
</select>
