Question

What is the method to apply custom styles (CSS) to individual options within a jQuery UI selectmenu?

When working with an HTML form that includes a select element, I encountered a design challenge.

<select id='myselect'>
<option value='1'>1</option>
<option value='2'>2</option>
...
<option value='N'>N</option>
</select>

To enhance the visual appeal of this form, I utilized jQuery UI:

$('#myselect').selectmenu();

Now, the task is to style the option corresponding to number 1 in a unique way. However, simply setting an id or class doesn't produce the desired result.

My approach involves several steps:

1) Construct the basic 'classic' select form in HTML

2) Integrate this 'classic' form with jQuery UI

3) Locate the specific element within the jQuery UI selectmenu (but how?)

4) Assign a new class name to the identified element

5) Apply CSS styling to the newly assigned class name

Thank you, Twisty, for pointing me in the right direction.

Here is my decision:

$.widget( "ui.selectmenu", $.ui.selectmenu, {
    _my_render: function( item ) {          
        return $("<div" + ((item.element[0].attributes.my_level == undefined) ? ("") : (" class = '_my_class'")) + ">" + item.label + "</div>");
    },

    _renderItem: function( ul, item ) {

        return $( "<li>" )
            .append(this._my_render(item))
            .appendTo(ul);
    },
});

You can find information about this in the API documentation: http://api.jqueryui.com/selectmenu/ specifically under the Theming section.

The selectmenu widget utilizes the jQuery UI CSS framework to style its appearance. If you need custom styling for selectmenu, you can use the following CSS class names to override or as keys for the classes option:

ui-selectmenu-button: The button-like element that replaces the native selectmenu on the page. It has the ui-selectmenu-button-closed class when closed, and the ui-selectmenu-button-open class when open.

ui-selectmenu-text: Represents the text portion of the button element.

ui-selectmenu-icon: Refers to the icon within the selectmenu button.

ui-selectmenu-menu: The wrapper element around the menu used to display options to the user (not the menu itself). When the menu is open, the ui-selectmenu-open class is added.

ui-selectmenu-optgroup: Represents one of the elements that replicates <optgroup> elements from native selects.

To see an example of this in action, you can visit: https://jqueryui.com/selectmenu/#custom_render

If you want to style specific items using CSS, you can hide the original select element and create an Unordered List (<ul>) to work with instead. You can then target items using proper jQuery or CSS selectors like #ui-id-1 or .ui-menu-item:first-child div.

It seems you have not shared any examples of what you've attempted or your end goal. Here's a basic example to get started: https://jsfiddle.net/Twisty/vgm3txh6/

HTML

<label for="number">Select a number</label>
<select name="number" id="number">
  <option>1</option>
  <option selected="selected">2</option>
  <option>3</option>
  ...
  <option>19</option>
</select>

CSS

.ui-menu-item:first-child {
  font-weight: bold;
}

JavaScript

$(function() {
  $("#number")
    .selectmenu()
    .selectmenu("menuWidget")
    .addClass("overflow");
});

If you provide more details or examples, I can offer further assistance. I hope this points you in the right direction towards finding a solution.
