Adding an 'Example Text' in Form Text Fields

Hi,

Thanks for your help.

I have got it working on text fields, but how do I do it for dropdown menus?

For text fields the code is:

<input name="name" type="text" class="formfield" id="name" placeholder="Example" />

But for the dropdown it is:

<select name="Size" class="formfield" id="Size">

My code for the Dropdown list is as follows:

<label for="size"></label>

          <span id="spryselect2">

          <label for="Size"></label>

          <select name="Size" class="formfield" id="Size">

<!--Connection to Other Table Start-->           

                 <option id="0">-- Select Size --</option>

                <?php

                    require("Connections/drama_database.php");

                    $getallequipsizes = mysql_query("SELECT * FROM equipsizes");                   

                    while($viewallequipsizes = mysql_fetch_array($getallequipsizes)){

                ?>

                <option id="<?php echo $viewallequipsizes['id']; ?>"><?php echo $viewallequipsizes['Size'] ?></option>

                <?php } ?>

<!--Connection to Other Table End--> 

          </select>

</span>
