I am using grid to show data of employee. I added auxheader to add filter to each column. I added property to columns tag - menupopup="auto". It is showing menu to each column.But when i hide some column from that menu, respective auxheader are still present in grid and hence mismatch occurs. Is their any way to hide respective auxheader with column or any another tag that i can use instead of auxheader ?? Thanks for help in advance.

Hello Ashutosh,

In order to accomplish your task, you have to set unique id's to the columns, and filters. Furthermore you have to set forward events for the menu items.

I have prepared for you a sample code below so you can see the logic:

-- index.zul

<zk>

 <menupopup id="editPopup">

    <menuitem id="subjectMenuItem" label="Subject" forward="onShowColumn(subject)" />
    <menuitem label="Received" forward="onShowColumn(received)" />  
    <menuitem label="Size" forward="onShowColumn(size)"/>
    <menuseparator />
</menupopup>

<grid id="inboxGrid" width="600px"  height="250px" 
    rowRenderer="pkg$.MyRowRenderer"
    emptyMessage="Nothing in Inbox.">

    <auxhead>
        <auxheader>
            <textbox id="subjectFilter" visible="true"></textbox>
        </auxheader>
    </auxhead>


    <columns menupopup="editPopup">
        <column id="subjectColumn" label="Subject" visible="true"/>
        <column width="50px" label="Received"  />
        <column width="80px" label="Size" />
    </columns>
</grid>

<!-- refresh content every 5 seconds -->
<timer id="timer" delay="2000" repeats="true" />

</zk>
