hi there :))
in the page u have:
<f:view>
    <h:form>
        <h:selectManyCheckbox layout="lineDirection" value="#{userBean.result}">
            <f:selectItems value="#{userBean.data}" />
        </h:selectManyCheckbox>
        <h:commandButton value="Submit" action="#{userBean.action}"/>
    </h:form>
</f:view>UserBean class:
        private String result[];
     private HashMap data;
     public String action() {
          if (result.length > 2) {
               for (String res : result) {
                    data.remove(res);
          return "";
     public HashMap getData() {
          if (data == null) {
               data = new HashMap();
               data.put("1", "1");
               data.put("2", "2");
               data.put("3", "3");
               data.put("4", "4");
               data.put("5", "5");
          return data;
     public String[] getResult() {
          return result;
     public void setResult(String[] result) {
          this.result = result;
     }in action method u check how many check boxes are clicked and if they`re more then 2 u delete them from the HashMap
