How to set a default value different from the available options using jQuery

<select id="itemDepartment">

  <option value="1">Computer Accessories</option>
  <option value="2">Laptop</option>

</select>

the default value in the drop-down list can be set using the selected="selected" attribute.

selected="selected"

Instead of selecting one of the options as the default, I want to display Please Select Department initially. When clicked, this text should disappear and the available options should appear (as is the default behavior).

Answer №1

<select id="itemDepartment">
    <option class="placeHolder" value=""> Please Choose Department </option>
    <option value="1">Office Supplies</option>
    <option value="2">Desk Accessories</option>
</select>​​​​​

$('#itemDepartment').focus(function() {
    $(this).find(".placeHolder").hide();
}).blur(function() {
    $(this).find(".placeHolder").show();
});​

See It in Action!

Answer №2

To implement this in your HTML, follow these steps:

<select id="itemDepartment">
    <option value="">Please Select Department</option>
    <option value="1">Computer Accessories</option>
    <option value="2">Laptop</option>
</select>

Next, incorporate the following JQuery script.

$(function () {
    $("#itemDepartment").click(function () {
        $("#itemDepartment option:first").css("display", "none");
    });

    $("#itemDepartment").blur(function () {
        $("#itemDepartment option:first").css("display", "block");
    });
});

Answer №3

If you want to display the text "Please Select Department" in a dropdown menu, you will need to include it as an option within the <select> element, typically as the first option.

<select id="itemDepartment">
  <option value="">Please Select Department</option>
  <option value="1">Computer Accessories</option>
  <option value="2">Laptop</option>
</select>

Any other method would require creating a custom <div> with JavaScript to mimic the behavior of a dropdown menu.

Answer №5

To create a new department selection dropdown, follow these steps:

<select id="newDepartment">
  <option value="" selected="selected">[Select Department]</option>
  <option value="1">Electronics</option>
  <option value="2">Home Goods</option>    
</select>
