Display Conditions
Dynamic variables are a key part of how apps in Frontly display, filter, and update information in real-time without coding.
They allow you to pull live data into blocks, labels, actions, and conditions by referencing values dynamically, adapting your app’s behaviour for each user and situation.
What Are Dynamic Variables?
Dynamic variables in Frontly are placeholders written using double curly braces {{ }}.
When the app loads, Frontly automatically replaces these placeholders with real data pulled from your user's session, a database record, the page, or other live context.
For example:
{{ user.firstName }}→ becomes the current user's first name.{{ record.email }}→ becomes the email field from a selected data record.{{ session.selectedCategory }}→ becomes the stored session value for filtering or personalization.
Important: Dynamic variables are case-sensitive and must be written exactly as shown.
Static Values vs Dynamic Values
When building your app, it's important to understand the difference between static values and dynamic values:
Type | Description | Example |
Static Value | A fixed value that never changes unless manually updated. |
|
Dynamic Value | A live, replaceable value that changes based on user data, page context, or app behaviour. | Welcome |
Static Values are useful when the content stays the same for everyone.
Dynamic Values personalize and automate the experience based on real-time data without needing manual updates.
Core Dynamic Variable Sources in Frontly
Namespace | Purpose | Example |
| Pulls data from the logged-in user's profile. |
|
| Pulls fields from a data record (List, Table, Kanban, etc.). |
|
| Refers to form values entered into specific fields. |
|
| Refers to temporary values set during the user's active session. |
|
Each namespace reflects a different "source of truth" within your app.
How to Use Dynamic Variables
You can use dynamic variables almost anywhere in Frontly:
Inside block text (e.g., labels, headers, button titles)
For conditions (e.g., hide/show a block only for certain users)
In actions (e.g., pass values to forms or clicked records)
In filtering (e.g., show only records matching an entered value)
They make your app flexible, personal, and responsive without needing to hard-code anything.
Examples
Scenario | How to use it | Result |
Personalize a Welcome Message |
| Displays "Hello, Nick!" |
Filter a List by Category | Hidden filter: | Shows only items in the selected category. |
Pass a Value to a Form | Default field value: | Pre-fills the form with the user's email stored in session. |
By mastering dynamic variables, you can accomplish a lot more in Frontly — creating apps that are smarter, faster, and deeply personalized for your users!
