    <p>Hi so in my JSF form I have three select boxes.This is the code:</p> <pre><code>&lt;h:form id="newRequestForm"&gt; &lt;h1&gt;New Request&lt;/h1&gt; &lt;br/&gt; &lt;h:panelGrid columns="4"&gt; &lt;h:selectOneMenu id="issueID" style="margin-left: 3px;" value="#{mycontroller.requestType}"&gt; --few items---- &lt;f:ajax event="change" listener="#{mycontroller.changeTypeList}" render="selectDevice" execute="@this" /&gt; &lt;/h:selectOneMenu&gt; &lt;br/&gt; &lt;div id="sessionDiv" columns="2"&gt; &lt;h:selectOneMenu id="selectRole" style="margin-left: 29px;" value="#{mycontroller.roleID}"&gt; &lt;f:selectItems value="#{mycontroller.roleList}" itemValue="#{mycontroller.roleList}"/&gt; &lt;/h:selectOneMenu&gt; &lt;/div&gt; &lt;div id="deviceDiv" columns="2"&gt; &lt;h:selectOneMenu id="selectDevice" style="margin-left: 18px;" value="#{mycontroller.userId}"&gt; &lt;f:selectItems value="#{mycontroller.deviceList}" var="device" itemValue="#{device.deviceId}"/&gt; &lt;/h:selectOneMenu&gt; &lt;/div&gt; &lt;div id="userDiv" columns="2"&gt; &lt;h:selectOneMenu id="selectUser" style="margin-left: 50px;" value="#{mycontroller.userIdReq}"&gt; &lt;f:selectItems value="#{mycontroller.usersList}" var="user" itemValue="#{user.userId}"/&gt; &lt;/h:selectOneMenu&gt; &lt;/div&gt; &lt;br/&gt; &lt;br/&gt; &lt;h:commandButton action="#{requestSupportController.submitRequest}" value="Submit Request" style="margin-top: 20px"/&gt; &lt;/h:form&gt; </code></pre> <p>Now when the form first loads the last three divs are hidden and based on the drop down values of the first div the reminaing divs are shown.Now in my ajax event I use render="selectDevice" which populates the values in that drop down.</p> <p>I actually have three scenarios: a)If the selected item in the first div is "Roles" all the roleId should be populated in the second div b)If the selected item in the first div is "Device" all the deviceID should be populated in the third div c)If the selected item in the first div is "Users" all the userIDshould be populated in the fourth div</p> <p>How can i achieve this as render can only render one div.When i used render="@form" then all divs are shown instead of being hidden.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
