Required Checkbox Validation for Elementor is the missing piece in Elementor Pro’s Form widget: the ability to make a checkbox field required.
Out of the box, Elementor Pro lets you mark text fields, email fields, and dropdowns as required — but there is no built-in required option for checkbox fields. This plugin fixes that gap with a single, clean toggle.
Enable the toggle on any checkbox field inside the Elementor Pro form editor, and the form will refuse to submit until at least one option is checked. Validation runs on both the client side (instant feedback before the AJAX request) and the server side (no bypass possible).
<h4>The problem this plugin solves</h4>
Imagine you have a consent form, a subscription preference form, or a survey with a checkbox group. You need users to select at least one option before the form can be submitted. With vanilla Elementor Pro, that is not possible — the checkbox field simply has no “required” setting. Every workaround (custom JavaScript, third-party form plugins, complex Elementor add-ons) introduces bloat, maintenance overhead, or layout conflicts.
This plugin solves the problem with zero configuration and zero bloat:
<ul>
<li>Install → Activate → Open your form → Toggle on.</li>
</ul>
<h4>Features</h4>
<ul>
<li>✅ Required toggle in the editor — a native-looking on/off switcher appears inside the form field settings, visible only for checkbox-type fields.</li>
<li>✅ Client-side validation — shows an inline error message instantly when a user tries to submit without selecting anything, before any network request is made.</li>
<li>✅ Server-side validation — a server-side guard ensures the requirement is enforced even if JavaScript is disabled or bypassed.</li>
<li>✅ Works with multiple checkbox fields — each checkbox field in a form is validated independently, so you can mix required and optional checkbox groups.</li>
<li>✅ Performance-first — the front-end CSS and JavaScript files are only loaded on pages that actually contain a form with at least one required checkbox. No extra load on any other page.</li>
<li>✅ Translation-ready — all user-facing strings are internationalised and ready for translation via translate.wordpress.org.</li>
<li>✅ No settings page — nothing to configure. The toggle is right where you need it: inside the Elementor editor.</li>
<li>✅ Graceful dependency checks — if Elementor or Elementor Pro is not active, a clear admin notice explains what is needed.</li>
</ul>
<h4>How to use</h4>
<ol>
<li>Make sure Elementor and Elementor Pro are installed and active.</li>
<li>Edit any page with an Elementor Pro Form widget (or add one).</li>
<li>In the Form Fields repeater, select or add a Checkbox field.</li>
<li>In the field’s Content tab, find the Required (at least one) toggle and switch it on.</li>
<li>Save and publish the page.</li>
</ol>
That’s it — the form will now block submission if the checkbox field is left empty.
<h4>Who is this for?</h4>
<ul>
<li>Agency developers building lead generation, consent, or survey forms.</li>
<li>Business owners running contact or booking forms that require service selection.</li>
<li>Freelancers who need a quick, clean solution without custom JavaScript.</li>
<li>Anyone using Elementor Pro forms who has ever needed a required checkbox.</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>WordPress 5.9 or higher</li>
<li>PHP 7.4 or higher</li>
<li><a href="https://wordpress.org/plugins/elementor/" rel="ugc">Elementor</a> (free) installed and active</li>
<li><a href="https://elementor.com/pro/" rel="nofollow ugc">Elementor Pro</a> (premium) installed and active</li>

<h3>Documentation</h3>
Dependencies are evaluated when customers attempt to add a product to their cart. If validation fails, the product cannot be added to the cart and a notice is displayed. In order to evaluate “Ownership”-type dependencies, customers are prompted to log in.
<h4>Creating Dependencies</h4>
To add dependencies to a product:
<ul>
<li>Go to the Product Data > Dependencies tab.</li>
<li>Use the Product Dependencies field to search for and add some products and/or variations.</li>
<li>Choose a Dependency Type.</li>
<li>Update to save your changes.</li>
</ul>
The “Ownership” dependency type is evaluated by checking if the customer has purchased a required product in a previous order. The “Purchase” dependency type requires the customer to have a required product in the cart in order to purchase the dependent one.
<h4>Ownership vs Purchase</h4>
The plugin allows you to select between 3 different dependency types:
<ul>
<li>Ownership: Access is granted only to customers that already own any of the products added to the Product Dependencies field.</li>
<li>Purchase: The product can be purchased only in combination with any of the items added to the Product Dependencies field. Ownership is not taken into account.</li>
<li>Either: Access is granted with ownership or purchase of any item added to the Product Dependencies field.</li>
</ul>

WooCommerce Product Dependencies

WooCommerce Product Dependencies is a well-built plugin that does one thing really well. It allows you to restrict the purchasing of a product unless certain other products have been purchased previously, or you have certain other products in your cart (and purchase them alongside the main product).

The UI fits right into the WooCommerce admin design. Super-simple options. Very clear how to use it. Great documentation on the WordPress plugin page.

And Jason provided fast & thorough support when I reached out with a question.

I'd highly recommend this plugin for anyone looking to set up WooCommerce product dependencies.

Works perfectly. Designed well. Does one thing really well.

Restrict access to any WooCommerce product, depending on the ownership and/or purchase of other required products.
