I created a list custom settings, and I need to add this into an existing picklist in my visualforce page.

I know how to display this list custom setting as a drop down in visualforce page, but I don't know how can I add this list into the existing picklist. When users select the picklist, and they can see this list custom settings as one of the picklist option.

My example based on the following settings:

  • Custom object: MyObject__c
  • A normal picklist: Picklist__c
  • Custom setting object: MySettingsList__c
  • Custom setting fields: Setting1 and Setting2

First i will read all values of the custom picklist and add it to the select option list. Then read the custom settings and add it to the list too.


public String selectedValue { get; set; }

public List<SelectOption> getMyOptions(){ 
    List<SelectOption> options = new List<SelectOption>();      

    // Reading picklist values and labels
    Schema.DescribeFieldResult fieldResult = MyObject__c.Picklist__c.getDescribe();
    List<Schema.PicklistEntry> picklistEntries = fieldResult.getPicklistValues();

    // Adding apicklist values to the select list
    for(Schema.PicklistEntry entry : picklistEntries){
        options.add(new SelectOption(entry.getValue(), entry.getLabel())); 

    // Now adding custom settings to the select list
    for(MySettingsList__c setting : MySettingsList__c.getAll().values()){
        options.add(new SelectOption(setting.name, setting.Setting1__c)); 
        options.add(new SelectOption(setting.name, setting.Setting2__c)); 

    return options;

Visualforce page:

<apex:selectList value="{!selectedValue}" size="1" multiselect="false">
    <apex:selectOptions value="{!MyOptions}"/>

Then it should look like this:

  • Is it possible to add the whole list custom setting into the drop down instead of the list custom setting fields? For example, I have two separate list custom settings, and each list will add into the drop down.

  • By using the above functionality we are getting as picklist but we need to display as in multiselect pick list.Here one is custom setting list and another is custom object multi-picklist value.I need to merge these two.
