Column-specific context menu for Primefaces DataTable

Solution

Have you tried(I have just tested with Primefaces 3.5): ContextMenu can be attached to any JSF component, each of rows in primefaces datatable has private and dynamic id(ex: :carList:0:test1 :carList:1:test1 ...), so I think you should use contextMenu inside column:

                 <p:column headerText="Model">  
                    <p:panel id="test1">
                        <h:outputText value="#{carr.model}" />
                        <p:contextMenu for="test1" widgetVar="cMenu">
                            <p:menuitem value="Edit Cell" icon="ui-icon-search"
                                        onclick="product.showCellEditor();return false;" />
                            <p:menuitem value="Hide Menu" icon="ui-icon-close"
                                        onclick="cMenu.hide()" />
                        </p:contextMenu>
                    </p:panel>
                </p:column>  
                <p:column headerText="MANUFAC" style="width:20%">  
                    <p:panel id="test2">
                        <h:outputText value="#{carr.manufacturer}" />
                        <p:contextMenu for="test2" widgetVar="cMenu2">
                            <p:menuitem value="Edit Cell" icon="ui-icon-search"
                                        onclick="product.showCellEditor();return false;" />
                            <p:menuitem value="Hide Menu" icon="ui-icon-close"
                                        onclick="cMenu2.hide()" />
                            <p:menuitem value="Hide Menu" icon="ui-icon-close"
                                        onclick="cMenu2.hide()" />
                        </p:contextMenu>
                    </p:panel>
                </p:column>

If you want to specify row:

<p:column headerText="Model" style="width:30%">  
                    <p:panel id="test1">
                        <h:outputText value="#{carr.model}" />
                        <p:contextMenu rendered="#{carr.model eq 'SENT'}" for="test1" widgetVar="cMenu">
                            <p:menuitem value="Edit Cell" icon="ui-icon-search"
                                        onclick="product.showCellEditor();return false;" />
                            <p:menuitem value="Hide Menu" icon="ui-icon-close"
                                        onclick="cMenu.hide()" />
                        </p:contextMenu>
                        <p:contextMenu rendered="#{carr.model eq 'WAITING'}" for="test1" widgetVar="cMenu3">

                            <p:menuitem value="Hide Menu" icon="ui-icon-close"
                                        onclick="cMenu3.hide()" />
                        </p:contextMenu>
                    </p:panel>
                </p:column>

Problem

How can I define context menu for each column differently in Primefaces datatable? Putting `<p:contextMenu>` inside `<p:column>` does not work properly. I want context menu to be different depending on which column user right-clicked in. This does not work (context menu is created the same for all columns): ``` <p:dataTable value="#{values}" var="value" selectionMode="single" selection="#{selectedValue}" id="table"> <p:column headerText="Col 1"> <h:outputText value="#{value.balance}"> <f:convertNumber type="currency"></f:convertNumber> </h:outputText> <p:contextMenu> <p:menuitem value="Report"></p:menuitem> <p:menuitem value="Change"></p:menuitem> </p:contextMenu> </p:column> <p:column headerText="col 2" > <h:outputText value="#{value.balance2}"> <f:convertNumber type="currency"></f:convertNumber> </h:outputText> <p:contextMenu> <p:menuitem value="Something else"></p:menuitem> </p:contextMenu> </p:column> </p:dataTable> ``` How to add column-specific context menu in Primefaces dataTable either by using PF components, extending PF components, or adding custom JavaScript?
