Progress indicator
A progress indicator guides users through any linear, multistep task by showing the user their completed, current, and future steps.

Overview
Progress indicators help manage a user’s expectations when completing a multistep process. They show which step the user is currently on, the total number of steps, and overall progress in completing a task.
Example of a progress indicator used in a payment UI.
When to use
- When the user is working through a linear process that can be organized into three or more steps.
- When the user could benefit from understanding their progress on long forms such as eCommerce checkouts, onboarding, or visa applications.
- When user inputs should be validated before progressing to the next step.
- To complement standard back/next navigation in a linear sequence.
When not to use
- When a process or form has fewer than three steps.
- When the process may be completed in any order.
- When the number of steps may change based on conditional logic.
Formatting
Anatomy
- Status indicator: Communicates if a step is completed, current, not started, disabled or has an error. See the status indicator pattern for guidance.
- Active step line: Indicates completed steps and the step the user is currently on.
- Label: Communicates what the user will accomplish in each step. Numbering each step also makes the progression more obvious.
- Inactive step line: Indicates steps that are not started as well as steps that are in an error, disabled, or skeleton state.
- Helper text: Labels a step as optional or in an error state.
Alignment
Progress indicators can be in vertical or horizontal positions depending on the use case and the structure of the UI. When possible, arrange the progress indicator vertically for easier reading.
Example of a progress indicator using vertical alignment.
Placement
The progress indicator component can be placed on a full page, in a modal, or in a side panel. It is also common to use the progress indicator in a tearsheet, a component provided by Carbon for IBM Products.

Content
Main elements
Label
The label should communicate what the user will accomplish in each step in one or two words. One option is to clearly indicate the action of the step by using the {verb} + {noun} content formula. For example, “Configure IdP” or “Define endpoints.” A label may use one word if it is universally understood, such as “Cart,” “Shipping,” or “Payment.” Avoid vague terms like “Processing.” You may also number each step to make the progression more obvious.
Helper text
Use the helper text to indicate that a step is optional or that a step is in an error state.
Overflow content
Label
When there is not enough space, consider rewording the label or truncate the label text with an ellipsis and provide a tooltip to convey additional information.
Helper text
Long helper text may wrap to a second line, and this is preferable to truncation. Wrap the helper text beneath the label so that both maintain left alignment.
Example of a helper text that wraps to the second line and maintains left alignment with the label.

Behaviors
States
The progress indicator has seven states: completed, current, not started, error, disabled, hover, and focus. View the Style tab for visual specs of each state and see the status indicator pattern for additional guidance.
| State | Description |
|---|---|
| Completed | A step is complete when a user has filled out the required information within a step and progressed to the following step. When possible, use validation to confirm that a step has been completed before the user continues. All steps that have been completed are indicated by an outlined circle with a checkmark and a blue active line. |
| Current | A step is current when a user is interacting with the information within that step. The current step the user is on is indicated by a half-filled circle and a blue active line. |
| Not started | A step is not started when a user has not yet interacted with that step. Steps the user has not encountered yet, or future steps, are indicated by an outlined circle and a gray active line. |
| Error | A step may be in error when a user has entered invalid or incomplete information. There could also be a server-side error. Provide clear information about the error and guidance on how to resolve the issue. |
| Disabled | A step is disabled when all interactive functions have been removed. Unlike read-only states, disabled states are not focusable, are not read by screen readers, and do not need to pass visual contrast, making them inaccessible if they need to be interpreted. |
| Hover | Use the hover state when a user’s mouse cursor is hovering over the progress indicator’s step. |
| Focus | When a user tabs to or clicks on the progress indicator’s step, the step becomes focused, indicating the user has successfully navigated to the component. |
Interactions
By default, the progress indicator is not interactive, providing only a visual update of the users’ progress. There is also an option for an interactive progress indicator, which allows users to navigate to each step.
Mouse
If the progress indicator is interactive, users can navigate to a step by clicking anywhere within the step label container.
Keyboard
The first step should be selected by default. Users can navigate between steps by pressing
Right
Left
Validation
When possible, use validation to confirm that a step has been completed before the user continues. If any entry is invalid, the progress indicator should show an error state. Additionally, the invalid entry should be marked with an error state and include an inline error message that helps the user understand the problem and how to fix it. This kind of inline validation (or client-side validation) should happen as soon as the field loses focus.
If the user cannot proceed due to a server-side issue, then an inline notification should appear.
Example of a progress indicator using validation.
