Hi,

I have createed a custom Field Country__c  in User Object with 10 values in it. How do I retrieve those values using SOQL in the controller and populate in <apex:selectOptions>. All those items must be displayed on the visualforce page so that I can make multiple selections.

Controller:

public class MyMSLController {
    String[] countries = new String[]{};
    User userObj = null;
    public MyMSLController(ApexPages.StandardController controller) {
    userObj = (User)controller.getRecord();
    
    
    }
public String[] getCountries()
{
return countries;

}

 public void setCountries(String[] countries) {
            this.countries = countries;
            
        }
        
 public List<SelectOption> getMyPickList()
{   
    List<SelectOption> options = new List<SelectOption>();
    List<User> usr= [ Select User.Country__c From  User];

    for(User a : usr){
        options.add(new SelectOption(??,??);
    }

    return options;
}

}

Visualforce page

<apex:page sidebar="false" showHeader="false" standardController="User" extensions="MyMSLController">
<apex:pageBlock ><apex:pageBlockSection ><apex:form >
<apex:outputLabel >Name:    </apex:outputLabel>
<apex:outputText value="{!$User.FirstName}"></apex:outputText><br/>
<apex:outputLabel >Select Countries:    </apex:outputLabel>
<apex:selectList value="{!countries}" multiselect="true" size="2" title="Select">
<apex:selectOptions value="{!myPickList}"></apex:selectOptions>
 </apex:selectList>
</apex:form>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:page>

Please suggest solution.
