Adding custom styles to dependent picklist fields in Visualforce pages.

Hi,

In this article i am trying to give small example of applying custom styles for dependent pick-list. Usually for dependent pick-list custom styles will not apply, So you have to do it forcefully.In this i am using bootstrap to apply the style for input elements.


You have to add the below script items in the vf page with the id's
 

Ex: 

<!-- https://salesforcedevil.wordpress.com/2015/07/16/me/ -->
<apex:page standardController="Account" standardStylesheets="false"  showHeader="false">
<apex:includeScript value="https://code.jquery.com/jquery-1.9.1.js"/>
     <apex:includeScript value="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"/>
     <apex:includeScript value="https://ajax.microsoft.com/ajax/jquery.validate/1.6/jquery.validate.min.js"/>   
    <apex:includeScript value="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"/>   
    <apex:stylesheet value="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"/>
   
   <apex:form >
    
            
 <apex:inputfield value="{!Account.Country__c}" styleClass="form-control"  />
  <div id="dependentlst1">  
 <apex:inputfield value="{!account.State__c}" styleClass="form-control" />
 
 </div>
 <div id="dependentlst2">
 <apex:inputfield value="{!account.City__c}" styleClass="form-control"/>
 </div>
 <script>
// MutationObserver detect changes in the document
var MutationObserver = window.WebKitMutationObserver || window.MutationObserver || window.MozMutationObserver;
var observer = new MutationObserver(function(mutations) {
// If the form-control was removed from the list – re-assign it
if(!$('#dependentlst1 select').first().hasClass('form-control')){
$('#dependentlst1 select').first().addClass('form-control');
}
if(!$('#dependentlst2 select').first().hasClass('form-control')){
$('#dependentlst2 select').first().addClass('form-control');
}
});

var dependentlst1 = document.querySelector('#dependentlst1');
var dependentlst2 = document.querySelector('#dependentlst2');
observer.observe(dependentlst1, {
childList: true,
subtree: true,
attributes: true
});
observer.observe(dependentlst2, {
childList: true,
subtree: true,
attributes: true
});
</script> 

   </apex:form>

</apex:page>
