In the Controller :

 

Query the course from database

 

public String selectedCourse{get; set;}

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

and iterate and add those values in a select option List

 

For(String courseName :  [select id,coursename from course where 'Your condition' ]){

courseList.add(new Selectoption(coursename,coursename) );

}

 

In the VF Page :

 

<apex:selectList size="1"  value="{!selectedCourse}" id="courselist" >
  <apex:selectOptions value="{!courseList}" ></apex:selectOptions>
   </apex:selectList>

 

This becomes a picklist without having to have relation between two objects.

Hi Ravi,

 

Yes it's possible.

 

Try below code without soql query.

 

first of all query the field in the Schema

Schema.DescribeFieldResult fieldResult = Student__c.courses__c.getDescribe();

 

Save this in a List

List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();

 

Iterate over list and get the label value pair

List<SelectOption> options = new List<SelectOption>();
for( Schema.PicklistEntry f : ple)
{
options.add(new SelectOption(f.getLabel(), f.getValue()));
}

 

In VF

 

<apex:selectList value="{!enquiry.SelectedCourses}" size="1" >
<apex:selectOptions value="{!options}"/>
</apex:selectList>
