Put this into your <BODY> section

<form>

<h1>Example 1</h1>
<div style="width:103px;width/* */:/**/100px;width: /**/100px;height:20px;border:1px solid #7F9DB9;">
	<input type="text" maxlength="7" style="width:80px;font-size:12px;height:17px;float:left;border:0px;padding-top:2px" name="rgb" size="10">
	<img style="float:right;padding-right:1px;padding-top:1px" src="images/select_arrow.gif" onmouseover="this.src='images/select_arrow_over.gif'" onmouseout="this.src='images/select_arrow.gif'" onclick="showColorPicker(this,document.forms[0].rgb)">
</div>


<h2>Simpler example 2</h2>

<table>
	<tr>
		<td><input type="text" size="10" maxlength="7" name="rgb2"></td>
		<td><input type="button" value="Color picker" onclick="showColorPicker(this,document.forms[0].rgb2)"></td>
	</tr>
</table>
</form>

Configuration

You simply assign an onclick event to an image or a button. Example
<input type="button" value="Color picker" onclick="showColorPicker(this,document.forms[0].rgb2)">

Download images
