how to get status and category value based on zone name in idea object salesforce

Question

This question only for users, who have knowledge about Idea object in salesforce For user who don't know about Idea object, I can't help .

how to get status and category value based on zone name in idea object salesforce

Requirement I have vf page. there I have three picklist

• Zone
• Category
• Status

But I am not getting filtered value when I am selecting A zone name from Zone picklist. It gives us all category and Status values.

But in standard sf page Idea detail page, It do these filtering. I want to do the same.

I have tried getting dependent field value using MetaData Api as well. but no luck because Zone(CommunityId-Apiname) is not dependent field of Status and Category field in Idea object, but behave in that manner(Magically).

ZoneId is label name and api name is CommunityId, is reference field in Idea obejct

Status and Category are picklist type of field and can have different-2 value depends upon Zone selection.

ZoneId is not controller field but behave like controller field for Status and Category field. This all are standard field(Category, Status, CommunityId(label as Zone)) and standard object(Idea)

In the end I would say,Zone is behaving as RecordType.

Zone Object detail page

Let me answer my question. It is possible using meta data describe pagelayout method.

<apex:outputPanel id="zoneFilter" layout="none">                          
    <h2 class="zoneLabel">Zone </h2> 
    <select title="Choose a Zone" style="width:22%;"  onchange="$('#zoneHidden input:first-child').val(this.value); changeDependentList(this.options[this.selectedIndex].innerHTML);">
            <option value="{!strZoneId}">{!strZoneName}</option>
                <apex:repeat id="repZone" value="{!lstZone}" var="objZone"  >                  
                    <apex:outputPanel id="optionZone" rendered="{!LOWER(objZone['label']) != LOWER(strZoneName)}" layout="none">
                        <option value="{!objZone['value']}">{!objZone['label']}</option>
                    </apex:outputPanel>
                </apex:repeat>
            </option>
    </select> 
    <span id="zoneHidden"><apex:inputHidden value="{!strZoneId}" /></span>         
</apex:outputPanel>

<apex:outputPanel id="categoryFilter" layout="none">  
    <h2>Category </h2>
    <select title="Choose a Categories" id="category" style="width:22%;"  onchange="$('#categoryHidden input:first-child').val(this.value);">

    </select>  
    <span id="categoryHidden"><apex:inputHidden value="{!strCategoryName}" /></span>  
</apex:outputPanel>              

<apex:outputPanel id="statusFilter" layout="none">           
    <h2 class="statusLabel">Status </h2>      
    <select title="Choose a Status"  id="status" style="width:22%;" onchange="$('#statusHidden input:first-child').val(this.value);"  >

    </select>  
    <span id="statusHidden"><apex:inputHidden value="{!strStatusName}" /></span>
</apex:outputPanel>
