We can show the picklist field value on Visualforce page in a selectlist ( dropdown) using the following code in the controller class:
public class classname {
public List<SelectOption> selectItemsList() {
List<SelectOption> selectOptions = new List<SelectOption>();
Schema.DescribeFieldResult describeResult = CustomObject__c.PickListFieldName__c.getDescribe();
List<Schema.PicklistEntry> pickListEntries = describeResult.getPicklistValues();
for( Schema.PicklistEntry eachEntry : pickListEntries) {
selectOptions.add(new SelectOption(eachEntry.getLabel(), eachEntry.getValue()));
}
return selectOptions;
}
}
In Visualforce page, we can use this using select list tag like this:
<apex:page controller=”classname”>
<apex:form>
<apex:selectList value=" " size="1" multiselect="false" >
<apex:selectOptions value="{!selectItemsList}">
</apex:selectOptions>
</apex:selectList>
</apex:form>
</apex:page>

how can we save if a user selects a specific option to that object
Create an apex variable in the controller with getter and setter to store the selected picklist value.
<apex:selectList value="{!apexVariableForSelectValue}" size="1" multiselect="false" ><apex:selectOptions value="{!selectItemsList}">
</apex:selectOptions>
</apex:selectList>
On Form submit (create a command button to submit form), you will get the selected value in the apex variable “apexVariableForSelectValue”. Use this value to store in any object you want.
