Example Multiple Choice Field

If i have understood it correctly, you have a multiple choice field on your page type and you wanted to pull the data out of it. Here is an example you can try to pull the data from multiple choice field from page type.

DataClassInfo classInfo = DataClassInfoProvider.GetDataClass("cms.news");
FormInfo formInfo = new FormInfo(classInfo.ClassFormDefinition);
FormFieldInfo ffi = formInfo.GetFormField("options");
Hashtable options = ffi.Settings;
string valuesWinTextXML = options["options"].ToString();

Also you can go with either custom macro or custom transformation method depending on where you're going to use it. This is where you could parse field value and retrieve appropriate data from database.

What Sultan provided is a pretty long way about getting this data out in a transformation. But like most things, there are multiple ways to do one thing. If you're in a transformation you can do something like so:

<script runat="server">
using System.Linq;
public string GetSplitValues()
{
    List<string> values = Eval<string>("ColumnName").Split("|").ToList();
    string returnValue = "";
    foreach (string s in values)
    {
        returnValue += "<li>" + s + "</li>";
    }
    return returnValue;
}
</script>

<ul>
    <%# GetSplitValues() %>
</ul>

Your output would look like the following:

• List item 1
• List item 2
• List item 3

Now if you have actual values or IDs in the list, you'd need to perform a lookup inside that foreach loop. This would then be better as a custom transformation method.
