Radio Button

A Radio Button in Bubble is a form element that lets users select one option from a predefined list. Only one option can be chosen at a time, making it ideal for exclusive choices.

It is a common UI element in forms, surveys, and preference settings where the user must commit to a single answer before submitting.

Key Takeaways

• Single selection only: Radio Buttons enforce one choice at a time, automatically deselecting the previous pick.
• Static or dynamic options: You can populate the options list with fixed text or dynamic data from your database.
• Easy to read values: The selected value is accessible in workflows and conditions just like any other input element.
• Built-in element: Bubble includes a Radio Buttons element in its core UI toolkit with no plugin needed.

What is a Radio Button in Bubble?

A Radio Button in Bubble is a UI input element that displays a list of options and allows the user to select exactly one. It is used when choices are mutually exclusive and the full list should be visible at once.

Radio Buttons are best used when you have a short list of options, typically two to six, and you want users to see all choices before deciding.

• Mutually exclusive selection: Choosing one option automatically unchecks all others in the same group.
• Visible options list: All options show at once, which helps users compare and decide without opening a dropdown.
• Label and value pairing: Each option can have a display label and a separate stored value to keep your data clean.

When your option list grows longer than six items, a dropdown usually gives a better user experience than a long Radio Button list.

How Radio Buttons Work in Bubble

Bubble's Radio Buttons element takes a list of choices and renders each as a selectable option. You configure the choices in the element's property editor and read the selected value in workflows or conditions.

Adding a Radio Button to your Bubble page is the same as adding any other element. Drag it onto the canvas and configure its choices in the right-side property panel.

• Static choices: Type a fixed list of options directly in the element settings when the choices will not change.
• Dynamic choices: Connect the element to a database search or option set to populate options from real data.
• Initial content: You can pre-select a default value so the element is not blank when the page loads.

The selected value is accessible via the element's state in conditions and workflows, making it easy to use in form submissions or page logic.

Why Radio Buttons Matter for No-Code Apps

Radio Buttons make forms clearer and reduce input errors by constraining users to valid choices. They are especially useful when the options are short, fixed, and require a clear single selection.

Good form design reduces user confusion and increases completion rates. Choosing the right input type for each field is part of that process.

• Reduces mistakes: Users cannot type invalid values when constrained to a predefined Radio Button list.
• Clearer than checkboxes: For single-choice questions, Radio Buttons communicate "pick one" more clearly than checkboxes do.
• Better than dropdowns for short lists: When you have three or four options, showing them all saves users a click.

According to research on form usability, Radio Buttons perform better than dropdowns for short, mutually exclusive option sets because users can compare all choices at once.

When to Use Radio Buttons vs. Other Inputs in Bubble

Use Radio Buttons when the user must pick exactly one option from a short, visible list. Use checkboxes for multi-select, dropdowns for long lists, and toggles for binary yes/no choices.

Choosing the wrong input type creates confusion and friction in your forms. Understanding when each type fits best leads to better app UX.

• Radio Buttons: Best for two to six mutually exclusive options that benefit from being visible simultaneously.
• Dropdowns: Better when you have seven or more options and need to save vertical space on the page.
• Checkboxes: Use when the user can legitimately pick more than one option from the same list.

Getting input types right is a small decision that has a big impact on how professional and usable your Bubble app feels to its users.
