Collapsible Sections in Gravity Forms, Fluent Forms, and Formidable: Compared

If you have decided to add collapsible sections to your WordPress forms, the next question is which plugin handles them best. Gravity Forms, Fluent Forms, and Formidable Forms all support the feature, but they implement it differently, charge differently, and behave differently in edge cases.

This comparison goes through each plugin honestly: how the feature works, what it costs, and where it falls short. By the end, you should know exactly which one fits your situation.

Quick Verdict

For most use cases, here is the short version:

• Fluent Forms Pro: Best built-in implementation. Cleanest UI, no add-on needed.
• Formidable Forms: Strong native support and good for data-heavy forms.
• Gravity Forms: Requires a paid third-party add-on, but the most flexible for complex logic.

Now the details, because the right choice depends on what else you need from the plugin.

Fluent Forms Pro

Fluent Forms added accordion and tab containers to its Pro version in late 2025. The feature is built into the form builder as a drag-and-drop container field. You drop an Accordion field into the form, then place input fields between the Start and Close markers.

What works well:

• No add-on or third-party purchase required. Pro covers it.
• Clean visual styling out of the box. Sections look right without custom CSS.
• Multiple display modes: connected (single accordion behavior, only one open) or disconnected (independent toggles).
• Mobile-optimized layouts by default.
• Tab variant for the same data, if you prefer horizontal navigation.

Where it falls short:

• Accessibility could be stronger. Keyboard navigation works, but screen reader announcements are basic.
• Conditional logic on the section level (showing or hiding entire sections based on earlier answers) is more limited than Gravity Forms.

Pricing: Fluent Forms Pro starts around $79 per year for a single site, with multi-site licenses going up from there. The accordion feature is included in all paid tiers.

Gravity Forms with the Collapsible Sections Add-On

Gravity Forms is the most established premium forms plugin in the WordPress ecosystem. It does not include collapsible sections in the core plugin. The Collapsible Sections add-on by JetSloth fills the gap.

What works well:

• Built on top of Gravity Forms’ Section field, so existing forms can be converted in minutes.
• Works seamlessly with conditional logic. Sections can be collapsible and conditionally visible at the same time.
• Nested logic is rock solid. If your form has complex branching, Gravity Forms handles it more reliably than the alternatives.
• Strong third-party ecosystem for payments, CRMs, and integrations.

Where it falls short:

• Two licenses required: Gravity Forms itself and the JetSloth add-on. Total cost adds up faster than the alternatives.
• Default styling needs CSS work to look modern.
• The form builder feels heavier than Fluent Forms, especially for simple use cases.

Pricing: Gravity Forms starts at $59 per year for the Basic license, but the Collapsible Sections add-on requires the Pro or Elite tier (around $159 to $259 per year). The add-on itself is around $39 to $79 per year on top.

Formidable Forms

Formidable includes a Collapsible Section field as part of the plugin itself, no add-on required. The implementation is straightforward: you add a Collapsible Section field, and any input fields below it (until the next section field) belong to that group.

What works well:

• Native support, no extra purchase needed at the right tier.
• Sections can default to expanded or collapsed based on form needs.
• Strong data handling features (Views, calculations, custom database tables) for forms that double as application logic.
• Good integration with conditional logic.

Where it falls short:

• The styling defaults are functional but plain. Custom CSS is usually needed to make sections feel polished.
• Mobile rendering is solid but not as refined as Fluent Forms.
• Pricing tier matters: the Collapsible Section field requires the Plus license or higher.

Pricing: Formidable Forms Plus starts at around $99 per year. The collapsible feature is included.

Side-by-Side Comparison

Here is how the three stack up across the dimensions that actually matter:

Ease of setup: Fluent Forms wins. Drag the field, fill in titles, done.

Visual polish out of the box: Fluent Forms wins again. Both Gravity Forms and Formidable need CSS work.

Complex conditional logic: Gravity Forms wins clearly. The Collapsible Sections add-on combined with Gravity Forms’ core logic engine handles edge cases the others stumble on.

Data and reporting: Formidable wins. Its Views and calculation features are unmatched in this set.

Total cost: Fluent Forms is the most affordable. Gravity Forms is the most expensive when you add the Pro license and the third-party add-on.

Mobile experience: Fluent Forms is best by default. The other two need more work to match. We cover the broader mobile considerations in our guide on mobile-friendly WordPress forms.

Which Should You Pick?

Run through these questions:

• Already using one of these plugins? Stay with it and use its native or add-on solution. Switching is rarely worth it.
• Starting fresh and want the easiest path? Fluent Forms Pro.
• Building a complex application with branching logic? Gravity Forms with the Collapsible Sections add-on.
• Building a form that doubles as a database (member directories, application tracking)? Formidable Forms.

And if you are weighing the layout pattern itself before committing to a plugin, our comparison of accordion versus multi-step forms is the right starting point.

When None of These Are the Right Fit

Sometimes the form requirements outgrow what any plugin can comfortably do. Custom integrations, unusual UX patterns, payment flows tied into bespoke business logic, all of these push you past the plugin frontier.

That is the territory where working with a custom WordPress development company like WPCustom makes sense. A bespoke form built around your actual workflow tends to outperform a plugin form forced to bend in three directions, especially when the form is your primary conversion path.

That said, the three plugins above cover 90 percent of real-world cases. Pick one, ship the form, measure the results, and only commission custom work if you genuinely hit the ceiling.
