I have a custom-list form with a list of countries:

  1. each country is a checkbox.
  2. Once the user clicks on the checkbox, a new textarea should appear.
  3. I need be able to save this on the custom-list, if the user checked 4 different countries, I need be able to retrieve all 4 textarea individually.

It's possible to do something like this on Sharepoint? What options do I have?

Sharepoint version: 15.0.4905.1000

  • Hi Mateus, can you specify the version of SharePoint you are referring to? – Denis Molodtsov Mar 9 '18 at 19:17
  • Hi @DenisMolodtsov 15.0.4905.1000 (I'll add on the description). Thanks. – Mateus Vahl Mar 9 '18 at 19:36
  • Oh, another question: do you need all 200+ countries? or you have a much smaller number? – Denis Molodtsov Mar 9 '18 at 19:42

We could do it by using many different approaches, but let's limit them to a couple:

First, start with creating 20 List columns. 10 for the countries and 10 for the respective text boxes. I suggest names like: CountryCanada, DescriptionCanada, CountrySpain, DescriptionSpain etc.

Approach #1. Add a Content Editor Webpart (CEWP) to the new, edit and display forms

This is just a simple example that would handle a single country, but you can improve it so that it works with as many as you want:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.10.2/jquery.min.js">

<script language="javascript" type="text/javascript">
$(document).ready(function () {
    var canadaCheckBox = $("input[ID^='CountryCanada']");

    var showOrHideField = function() {
        if(canadaCheckBox.is(':checked')) {                

    // run at startup (for edit form)
    // make sure when the user changes the value - we handle it:
    $(canadaCheckBox).on('change', showOrHideField);


function hideField(fieldInternalName) {
    return $("h3#" + fieldInternalName).parent().parent().hide();

function showField(fieldInternalName) {
    return $("h3#" + fieldInternalName).parent().parent().show();

function getField(fieldInternalName) {
    return $("h3#" + fieldInternalName).parent().parent();


Approach #2. Use AngularJs

If you know AngularJs - you can use it to create your custom and good looking forms from scratch: https://github.com/Zerg00s/AngularForms

You can also try using InfoPath, SPServies or to modify the existing form using SharePoint Designer, but I only like the first two approaches.

  • I'm looking for something like option 1, but the problem for me is: 1. The list of countries is checkbox dynamic, so I cannot add static information like "CountryCanada". 2. Later, I'll need recover information about all country descriptions via javascript API. So I will need figure out which description belong to each country. Thanks for the help. – Mateus Vahl Mar 9 '18 at 20:07
