Accordions are essential components of modern web design.

They help organize content in an interactive and compact manner, enhancing user experience.

HubSpot, as a versatile CMS and marketing platform, provides functionality to implement accordions.

However, ensuring that only one accordion remains open at a time can sometimes be a challenge.

This blog will walk you through how to force only one accordion open in HubSpot. We’ll cover actionable examples and tips to keep your implementation smooth.

Why Use Accordions in HubSpot?

Accordions make your HubSpot pages cleaner and more organized.

They’re useful for FAQs, pricing breakdowns, or detailed explanations. By limiting the open state to one accordion, you can:

• Improve readability.
• Prevent content clutter.
• Enhance user navigation.

Now, let’s explore step-by-step instructions on implementing a single-open accordion in HubSpot.

How to Force Only One Accordion Open in HubSpot​ Using JavaScript

To force only one accordion open in HubSpot, you’ll need to tweak the default behavior. HubSpot allows you to embed custom JavaScript within your pages or templates.

Insert Accordion Markup

Ensure your accordion HTML structure is set up correctly. A structure might look like this:

<div class=”accordion”>
<div class=”accordion-item”>
<button class=”accordion-header”>Accordion 1</button>
<div class=”accordion-content”>Content for Accordion 1</div>
</div>
<div class=”accordion-item”>
<button class=”accordion-header”>Accordion 2</button>
<div class=”accordion-content”>Content for Accordion 2</div>
</div>
</div>

Add Custom JavaScript

Use JavaScript to manage the open and close states. Here’s an example:

document.addEventListener(‘DOMContentLoaded’, () => {
const accordionHeaders = document.querySelectorAll(‘.accordion-header’);

accordionHeaders.forEach(header => {
header.addEventListener(‘click’, () => {
const openItem = document.querySelector(‘.accordion-item.open’);

// Close any already open accordion
if (openItem && openItem !== header.parentElement) {
openItem.classList.remove(‘open’);
openItem.querySelector(‘.accordion-content’).style.maxHeight = null;
}

// Toggle the clicked accordion
const content = header.nextElementSibling;
if (!header.parentElement.classList.contains(‘open’)) {
header.parentElement.classList.add(‘open’);
content.style.maxHeight = content.scrollHeight + ‘px’;
} else {
header.parentElement.classList.remove(‘open’);
content.style.maxHeight = null;
}
});
});
});

Apply CSS for Styling

Ensure the accordion looks professional with proper styling:

.accordion-content {
max-height: 0;
overflow: hidden;
transition: max-height 0.3s ease-out;
}
.accordion-item.open .accordion-content {
max-height: 500px; /* Adjust based on content */
}

Where to Add the Script

You can add this script in the HTML + HubL module of your HubSpot page or template.

Use the HubSpot Design Manager to include the JavaScript file.

If coding isn’t your strong suit, HubSpot’s drag-and-drop editor offers an alternative.

Here’s how:

Navigate to Design Manager

Go to Marketing > Files and Templates > Design Tools.

Create a Custom Module

Add a module for your accordion structure.

Use HubL to repeat elements dynamically.

Customize Behavior

HubSpot’s module editor allows you to add JavaScript in the module settings to control the accordion’s behavior.

When building dashboards, use a similar approach by leveraging HubSpot’s API to populate accordion content.

For instance:

hubspot.getData(‘dashboard-data’).then(data => {
// Populate accordion content dynamically based on dashboard data
});

For more advanced requirements, consider integrating libraries like Bootstrap.

Bootstrap accordions come pre-built with support for a single open accordion.

Include Bootstrap

Add the Bootstrap CSS and JS files to your HubSpot page.

Implement Bootstrap Accordion

Use the following markup:

<div class=”accordion” id=”hubspotAccordion”>
<div class=”accordion-item”>
<h2 class=”accordion-header” id=”headingOne”>
<button class=”accordion-button” type=”button” data-bs-toggle=”collapse” data-bs-target=”#collapseOne”>
Accordion 1
</button>
</h2>
<div id=”collapseOne” class=”accordion-collapse collapse show”>
<div class=”accordion-body”>Content for Accordion 1</div>
</div>
</div>
</div>

Customize Behavior

Bootstrap handles the single-open state by default, so minimal additional scripting is required.

How to Force Only One Accordion Open in HubSpot Forms

Add collapsible sections in your HubSpot forms to make them visually appealing and less overwhelming.

For example, use accordions to hide non-essential fields until necessary.

While email clients have limited support for advanced JavaScript, you can simulate accordion functionality by using anchor links or conditional content blocks.

hubspot.client.crm.deals.basicApi.getAll().then(response => {
// Populate accordions with deal data
});

Troubleshooting Tips

Accordions Not Closing Properly

Ensure no conflicting scripts are present.

HubSpot Limitations

Use workarounds like third-party libraries if native HubSpot functionality doesn’t suffice.
