Hide dependent field when picklist value is none

Hi,

I created a VF page where, checkbox appears dependent on the value of the picklist. For Example

Picklist vlaues are: Meets Best Practices, Partially Meets Best Practices, Doesnot Meet Best Practices. For each Picklist value a checkbox appears. My Problem here is when the picklist value is "none" then all the checkbox appear. I want then to appear only when picklist value is selected and hide all checkbox when the picklist value is none.

Here is the code: 
<apex:pageBlockSection collapsible="false" columns="1" title="Instructional Material">
<apex:inputField value="{!Class__c.QC_Material_Observation__c}" required="false">
<apex:actionsupport event="onchange" rerender="null,best,partial,doesnot"/>
</apex:inputField>
<apex:outputPanel >

</apex:outputPanel>
<apex:outputPanel id="best" >
<apex:pageBlockSection rendered="{!Contains(Class__c.QC_Material_Observation__c,'Meets Best Practices')}" >
<apex:inputCheckbox value="{!Class__c.QC_IM_Fine__c}"/>
<apex:inputCheckbox value="{!Class__c.QC_IM_Fine_Multimedia__c}"/>
</apex:pageBlockSection> 
</apex:outputPanel>

<apex:outputPanel id="partial" >
<apex:pageBlockSection rendered="{!Contains(Class__c.QC_Material_Observation__c,'Partially Meets Best Practice')}" >
<apex:inputCheckbox value="{!Class__c.QC_IM_Fine_Multimedia__c}"/>
</apex:pageBlockSection> 
</apex:outputPanel>

<apex:outputPanel id="doesnot" >
<apex:pageBlockSection rendered="{!Contains(Class__c.QC_Material_Observation__c,'Does not Meet Best Practices')}" >
<apex:inputCheckbox value="{!Class__c.QC_Third_Party_Material__c}"/>
<apex:inputCheckbox value="{!Class__c.QC_No_Lectures__c}"/>
</apex:pageBlockSection> 
</apex:outputPanel>
</apex:outputPanel> 

<apex:inputTextarea value="{!Class__c.QC_Material_Comments__c}" required="false" rows="10" cols="50" />
<apex:inputField value="{!Class__c.QC_Material_Score__c}" required="false"/>
</apex:pageblocksection>

Please add the condition to whether the picklist value is none in all pageblocksection and based on it render it

 

For ex :

 

<apex:pageBlockSection rendered="{!Class__c.QC_Material_Observation__c=='Meets Best Practices'  }" >

 

similarly add this condition for other pageblock section tags.

 

Let me know if it didn't work

Hi 

 

try this

 

 Please remove this line in code.

 

<apex:actionsupport event="onchange" rerender="null,best,partial,doesnot"/>

It worked when i slightly changed the condition. 

 

<apex:outputPanel id="best1" >
<apex:inputfield rendered="{!Class__c.QC_Material_Observation__c=='Meets Best Practices'}" >
<apex:inputCheckbox value="{!Class__c.QC_IM_Fine__c}"/>
<apex:inputCheckbox value="{!Class__c.QC_IM_Fine_Multimedia__c}"/>
</apex:inputfield>
</apex:outputPanel>

That Line is important to rerender. But yes I removed "Null " from that line. Thanks anyways
