Configure the appearance of GWT ListBox elements

Is it possible to customize the CSS style of individual items in a GWT ListBox drop-down menu? For example, changing the color of certain items. I am unable to achieve this by applying a style to the entire ListBox because I need a different style for each item! The desired result would look like this:

<select class="style1" id="test">
  <option class="style2" value="">&nbsp;</option>
  <option class="style2" value="AL">Alabama</option>
  <option class="style6" value="AK">Alaska</option>
  <option class="style6 red" value="AZ">Arizona</option>
  <option class="style6" value="AR">Arkansas</option>
  <option value="CA">California</option>
  <option value="CO">Colorado</option>
  <option value="CT">Connecticut</option>
  <option value="DE">Delaware</option>
 </select>

Answer №1

Experiment by using 

options.getItem(i).getStyle().setColor("#FF0000");

ListBox listBox = new ListBox();
//Add item to the listBox.
SelectElement selectElement = SelectElement.as(listBox.getElement());
NodeList<OptionElement> options = selectElement.getOptions();

for (int i = 0; i < options.getLength(); i++) {
     options.getItem(i).getStyle().setColor("#FF0000");
}

Answer №2

During my exploration, I once delved into this very question. I encountered difficulty in altering the appearance of individual ListBox elements, focusing instead on the general list.

Through my investigations, I remembered encountering alternative GWT-based libraries boasting more advanced widgets equipped with such inherent capability (such as GXT or Sencha, if my memory serves me right).

From a pure GWT standpoint, it seems that utilizing CellList could be one possible approach.

Answer №3

Although I attempted this in the past, I was unable to find a solution to make it function solely with GWT.

However, there are several third-party JavaScript frameworks that can help achieve this. You may explore the following links:

Answer №4

To give that bad boy some flair, apply some CSS magic:

.my_choice { style rules for control here } .my_choice option { text-color: #ffffff; bg-color: #000000 }
