Mastering Custom States in Bubble.io to Build Smarter Dynamic Interfaces
Custom states are one of the most powerful — and most underused — features in Bubble.io. Learn how to use them to create fluid, responsive UIs without touching your database.
What Are Custom States in Bubble.io?
If you have spent any meaningful time building in Bubble.io, you have probably hit a wall where you needed your app to remember something temporarily — like which tab a user clicked, whether a modal is open, or what item in a list is currently selected. That is exactly what custom states are designed to solve.
Custom states in Bubble.io are temporary, in-memory variables you can attach to any element on your page. They do not write to the database. They do not persist after a page refresh. They exist only for the duration of a user’s current session on that page — and that is precisely what makes them so useful for building dynamic, interactive user interfaces.
Think of a custom state as a sticky note attached to an element. You write a value on it, other elements can read it, and your workflows can change it. When the user leaves the page, the note disappears. No database overhead, no server round-trips, no latency.
When Should You Use Custom States?
Founders and product builders often default to saving everything in the Bubble database, even when the data only needs to live for a few seconds of user interaction. This creates unnecessary API calls, slower workflows, and a messier data model. Custom states solve all of that.
Here are the most common scenarios where custom states are the right tool for the job — and why reaching for the database instead would be a costly mistake.
Tab & Menu Navigation
Store the active tab name as a text state and conditionally show or hide content groups. No page reloads, no database queries — instant switching.
Modal & Popup Control
Use a yes/no state to toggle modals, side drawers, or overlay panels. This gives you full control over visibility logic with simple conditionals.
Multi-Step Forms
Track which step of a form the user is on with a number state. Increment it on “Next” and decrement it on “Back” — zero database writes required.
Live Search & Filtering
Store a search input value or selected filter as a state, then feed it directly into a repeating group’s search constraints for real-time filtering.
Selected Item Tracking
In a product list or dashboard, store the currently selected item’s unique ID as a state. Use it to highlight the active card and display its details in a side panel.
Theme & Mode Toggles
Flip between dark mode and light mode, or toggle between a grid and list view, using a yes/no or text state. Style conditionals do the rest.
How to Create and Use Custom States in Bubble.io
Setting up a custom state takes less than two minutes once you know where to look. The process is consistent regardless of which element type you attach the state to — buttons, groups, repeating groups, or even the page itself. Here is a clear walkthrough.
Select the Element to Attach the State To
Click on any element in the Bubble editor — typically a Group or the Page element itself is the best choice for page-level states. Right-click and choose “Add a custom state” from the context menu, or click the element name in the left sidebar and look for the states option.
Name Your State and Set Its Data Type
Give the state a descriptive name — something like “active_tab”, “is_modal_open”, or “selected_product”. Then choose its data type: text, number, yes/no, date, or even a custom data type from your database schema. Set a default value if needed.
Set the State Value in a Workflow
Create a workflow on any trigger — a button click, page load, or input change. Add the action “Set state” and point it at your element and state name. Enter the value you want to assign. This is how your app writes to the state.
Reference the State in Conditionals and Dynamic Data
Now use the state’s value anywhere Bubble accepts dynamic data. In an element’s conditional panel, reference it like this: “Element’s [state name]”. You can show/hide elements, change styles, filter repeating groups, or populate text fields based entirely on this in-memory value.
Reset States When Needed
Custom states persist for the session, so remember to reset them when the user closes a modal, submits a form, or navigates away from a section. Use the “Set state” action with your default value, or use the built-in “Reset relevant inputs” action to clear form-related states cleanly.
Pro Tip: Attach States to the Page Element for Global Access
If multiple sections or groups on a page need to read the same state, attach it to the Page element rather than a specific group. This makes the state globally accessible from any element on that page without needing to chain references through parent elements.
Custom States vs. Database Fields: Knowing the Difference
One of the most common mistakes we see when auditing Bubble apps at SA Solutions is builders using database fields to store values that should be custom states — and vice versa. Getting this distinction right has a direct impact on your app’s performance, scalability, and monthly Bubble plan costs.
Use custom states for anything that is temporary, user-specific to the current session, and does not need to survive a page refresh. Use the database for anything that must be stored permanently, shared across users, or retrieved in future sessions.
| Scenario | Use Custom State | Use Database |
|---|---|---|
| Active tab on a dashboard | ✅ Yes | ❌ No |
| User’s preferred theme | ⚠️ Session only | ✅ If persistent |
| Selected item in a list | ✅ Yes | ❌ No |
| Form submission data | ❌ No | ✅ Yes |
| Multi-step form progress | ✅ Yes | ❌ No |
| Filter/search query | ✅ Yes | ❌ No |
| User profile information | ❌ No | ✅ Yes |
If you are unsure whether to use a custom state or a database field in your current build, that is exactly the kind of architectural decision our team helps founders work through during a Discovery Sprint — before a single workflow is built the wrong way.
The Business Case for Getting Custom States Right
This might seem like a purely technical topic, but it has real business consequences. Apps that overuse database reads for UI state are slower, more expensive to scale, and harder to maintain. Slow apps lose users — it is that simple. A one-second delay in load time can reduce conversions by up to 7%, and no-code apps are not immune to that reality.
When our team at SA Solutions builds products for startups and growth-stage companies, custom state architecture is baked into the design from day one. We treat UI state management as a product performance feature, not an afterthought.
