How to Display Select Box Options on Hover Instead of Clicking?

Hovering to Display Select Box Options

The issue presented involves creating a select box that displays options on hover instead of after clicking. The code provided is a simple select box:

<select name="size">
   <option value="small">Small</option>
    <option value="medium">Medium</option>
    <option value="large">Large</option>
</select> 
Copy after login

Solution

The provided jQuery solution aims to achieve the desired behavior:

$('#selectUl li:not(":first")').addClass('unselected');
$('#selectUl').hover(
    function(){
    $(this).find('li').click(
        function(){
            $('.unselected').removeClass('unselected');
            $(this).siblings('li').addClass('unselected');
            var index = $(this).index();
            $('select option:selected').removeAttr('selected');
            $('select[name=size]')
                .find('option:eq(' + index + ')')
                .attr('selected',true);
        });
    },
    function(){
});
Copy after login

Explanation

  • The code initially hides all options except the first one by adding the "unselected" class.
  • Upon hovering over the ul, it enables clicking on the options to change the selection.
  • Clicking an option removes the "unselected" class from all others and adds it to the clicked option, ensuring it remains visible.
  • The selected option's index is used to update the select element, making the change persistent.

Additional Features

The solution has been extended to include:

  • An alert to demonstrate the updated select element's value.
  • Styling to improve the visibility of the selected and hovered options.
  • A plug-in approach for easier implementation in other projects.
  • A guidance text element to explain the purpose of the select box.
