I'm working on a custom object merge feature and am having difficulty replicating the standard SF merge UI. I'm hoping to use <apex:selectRadio> to display field values on a row, with the columns representing the different records. The radio option value (value attribute in <input type="radio">) would contain the record Id and the option label the field value. That way, when merging, I can just pull the <apex:selectRadio> value and know which record to copy the field data from.

I cannot get <apex:selectRadio> to display the field values correctly within a row because it outputs a <fieldset> containing a <table> .

Anyone done this using <apex:selectRadio>? Any other approaches/suggestions welcome.

For those not familiar with SF's standard merge UI, here it is:

enter image description here

Here's what I've tried so far:


<apex:page standardController="Widget__c" extensions="WidgetMergeExt" showHeader="true" sidebar="true" recordSetVar="widgets">

      <apex:pageBlockTable value="{!fields}" var="field">
          <apex:selectRadio value="{!field.radioValue}">
            <apex:selectOptions value="{!field.options}"/>



public with sharing class WidgetMergeExt {

    private ApexPages.StandardSetController setCon;
    public List<String> fieldNames {get; set;}
    public List<Field> fields {get; set;}

    public WidgetMergeExt(ApexPages.StandardSetController setCon) {
        this.setCon = setCon;
        fieldNames = new List<String> {'Name','CreatedDate','LastModifiedDate'};
        fields = new List<Field>();
        List<Widget__c> widgetsToMerge = [ SELECT Name,CreatedDate,LastModifiedDate FROM Widget__c WHERE Id IN :setCon.getSelected() ];
        for (String fieldName : fieldNames) {
            List<SelectOption> options = new List<SelectOption>();
            for (Widget__c widget : widgetsToMerge) {
                String value = String.valueOf(widget.Id);
                String label = String.valueOf(widget.get(fieldName));
                options.add(new SelectOption(value, label));
            fields.add(new Field(options));

    class Field {
        public List<SelectOption> options {get; set;}
        public String radioValue {get; set;}
        public Field(List<SelectOption> options) {
            this.options = options;
            this.radioValue = '';

Because <apex:selectRadio> outputs a table, the result is a single-column table with the column containing the selectRadio-generated table with a for each option like so:

(example row)

  <tr class="dataRow even  first" onmouseover="if (window.hiOn){hiOn(this);} " onmouseout="if (window.hiOff){hiOff(this);} " onblur="if (window.hiOff){hiOff(this);}" onfocus="if (window.hiOn){hiOn(this);}">
    <td class=" dataCell  " id="j_id0:j_id1:j_id2:j_id3:0:j_id4" colspan="1">
      <fieldset style="border: none;">
        <table role="presentation">
                <input type="radio" name="j_id0:j_id1:j_id2:j_id3:0:j_id5" id="j_id0:j_id1:j_id2:j_id3:0:j_id5:0" value="a0KM0000009OusKMAS">
                <label for="j_id0:j_id1:j_id2:j_id3:0:j_id5:0">Test Record 1</label>
                <input type="radio" name="j_id0:j_id1:j_id2:j_id3:0:j_id5" id="j_id0:j_id1:j_id2:j_id3:0:j_id5:1" value="a0KM0000009OusLMAS">
                <label for="j_id0:j_id1:j_id2:j_id3:0:j_id5:1">Test Record 2</label>
                <input type="radio" name="j_id0:j_id1:j_id2:j_id3:0:j_id5" id="j_id0:j_id1:j_id2:j_id3:0:j_id5:2" value="a0KM0000009OusMMAS">
                <label for="j_id0:j_id1:j_id2:j_id3:0:j_id5:2">Test Record 3</label>

The Salesforce Foundation's Nonprofit Starter Pack has a custom merge functionality with a "paint your own record" type UI. The code is open source. Here is a good overview of the functionality:
