How can I create custom picklist on a Salesforce Visualforce Page?

Hi Ankit,

VF Page

<apex:page tabStyle="Case" controller="customPicklist">
<apex:form >
<apex:pageBlock title="Custom PickList Demo" id="out">
<apex:pageBlockButtons >
<apex:commandButton value="Save" action="{!save}" rerender="out" status="actStatusId"/>
<apex:actionStatus id="actStatusId">
<apex:facet name="start">
<img src="/img/loading.gif" />
</apex:facet>
</apex:actionStatus>
</apex:pageBlockButtons>
<apex:pageBlockSection title="Custom Picklist Using selectList and selectOptions">
<apex:selectList value="{!selectedCountry2}" multiselect="false" size="1">
<apex:selectOptions value="{!countriesOptions}"/>
</apex:selectList>
<apex:outputText value="{!selectedCountry2}" label="You have selected:"/>
</apex:pageBlockSection>
</apex:pageBlock>
<apex:pageBlock >

</apex:pageBlock>
</apex:form>
</apex:page>

-------------------------------------------------------------

Apex Controller Class

public with sharing class customPicklist {
public String selectedCountry2{get;set;}
public List<String> selectedCategories { get; set; }

public List<SelectOption> getCountriesOptions() {
List<SelectOption> countryOptions = new List<SelectOption>();
countryOptions.add(new SelectOption('','-None-'));
countryOptions.add(new SelectOption('INDIA','India'));
countryOptions.add(new SelectOption('USA','USA'));
countryOptions.add(new SelectOption('United Kingdom','UK'));
countryOptions.add(new SelectOption('Germany','Germany'));
countryOptions.add(new SelectOption('Ireland','Ireland'));

return countryOptions;
}

public List<SelectOption> getCategories() {

List<SelectOption> categories = new List<SelectOption>();

for(Case c : [Select sahi__MultiSelectPicklist__c from Case limit 10])

categories.add(new SelectOption(c.sahi__MultiSelectPicklist__c, c.sahi__MultiSelectPicklist__c));

return categories;

}
public PageReference save(){
return null;
}

}

Hope this helps you.
