"Dependent Drop-Down Combo Box Lists In many situations, you will have two combo boxes, with the contents of the second dependent on the value selected in the first. That is, each item in the first combo box is associated with a list. To handle this, you need for the first combo box to do a submit when it changes, so that you have a chance to update the second. You do this with: <html:select property="orgId" onchange='document.forms[0].submit()'> <html:options collection="orgList" property="value" labelProperty="longName"/> </html:select> In this example, the property "value", of the beans in orglist are orgIds and the "labelProperty" property is the name to display. When you are in your action class the first time, the orgId string property of your form bean will be null or blank. In subsequent submissions the orgId property of your form bean will contain a valid orgId, so that you can look up the list associated with that value, and thus populate the second drop-down combo box propery.
