Progressive Disclosure

Progressive Disclosure - Show the Right Thing at the Right Time

Progressive Disclosure is an interaction design technique that sequences information and actions across time, showing users only what they need when they need it. It reduces cognitive load by deferring complexity until the user is ready for it.

When to Use This Skill

• Designing onboarding for complex products
• Simplifying feature-rich interfaces
• Creating multi-step forms and wizards
• Building admin panels and settings pages
• Introducing new features to existing users
• Reducing support requests and confusion

Core Concepts

The Hierarchy of Disclosure

Level 0: Essential (always visible)
    |
    v
Level 1: Important (one click away)
    |
    v
Level 2: Useful (accessible but hidden)
    |
    v
Level 3: Advanced (buried intentionally)

80/20 Rule Applied

80% of users need 20% of features. Show that 20% prominently, progressively reveal the rest.

+------------------------------------------+
|  Primary Actions (20%)                   |
|  [Action 1] [Action 2]                   |
+------------------------------------------+
|  v Advanced Options                      |
|    +------------------------------------+|
|    | Secondary (30%)                    ||
|    | [Option 3] [Option 4]              ||
|    +------------------------------------+|
|    |  v More Options                    ||
|    |    +------------------------------+||
|    |    | Tertiary (50%)              |||
|    |    | [Rare settings...]          |||
|    |    +------------------------------+||
|    +------------------------------------+|

Types of Progressive Disclosure

Analysis Framework

Step 1: Audit Current Interface

List all elements users see:

Step 2: Categorize by Priority

                    HIGH
                     |
    +----------------+----------------+
    |                |                |
    |  ESSENTIAL     |  CONTEXTUAL    |
    |  Always show   |  Show when     |
    |                |  relevant      |
FREQUENCY           |                NEED
    |                |                |
    |  ACCESSIBLE    |  HIDE          |
    |  One click     |  Deep menus    |
    |  away          |                |
    +----------------+----------------+
                     |
                    LOW

Step 3: Design Disclosure Pattern

Step 4: Test Understanding

• Can users complete primary tasks without expanding?
• Can users find advanced features when needed?
• Is the "expand" affordance clear?

Output Template

## Progressive Disclosure Design

**Interface:** [Name] **Date:** [Date]

### Element Inventory

| Element | Priority  | Disclosure Level | Reveal Trigger |
| ------- | --------- | ---------------- | -------------- |
| [E1]    | Essential | Always visible   | -              |
| [E2]    | Important | Level 1          | [Trigger]      |
| [E3]    | Advanced  | Level 2          | [Trigger]      |

### Disclosure Hierarchy

**Level 0 (Always visible):**

- [Element list]

**Level 1 (One interaction):**

- Trigger: [How user reveals]
- Contents: [Element list]

**Level 2 (Two interactions):**

- Trigger: [How user reveals]
- Contents: [Element list]

### User Flow

1. User sees: [Initial state]
2. To access [feature], user: [Action]
3. System reveals: [New state]

### Success Metrics

| Metric               | Before  | After Target |
| -------------------- | ------- | ------------ |
| Task completion rate | [X%]    | [Y%]         |
| Time to complete     | [X sec] | [Y sec]      |
| Support tickets      | [X/mo]  | [Y/mo]       |

Real-World Examples

Example 1: Gmail Compose

Level 0: To, Subject, Body, Send Level 1: CC, BCC (click "Cc" to reveal) Level 2: Formatting toolbar (click "A" to reveal) Level 3: Confidential mode, schedule send (menu)

Most users never need CC/BCC, so it's hidden by default.

Example 2: Notion Properties

Level 0: Page title and content Level 1: Basic properties (click to expand) Level 2: Add property, configure property Level 3: Database views, relations, rollups

New users see a simple page; power users unlock complexity.

Example 3: iPhone Camera

Level 0: Shutter button, switch camera Level 1: Swipe for modes (Video, Portrait, etc.) Level 2: Tap for exposure/focus controls Level 3: Settings app for advanced options

Best Practices

Do

• Make primary actions immediately visible
• Use clear affordances for expanding ("Show more", arrows)
• Remember user preferences for disclosure state
• Provide search/filter for deeply hidden features
• Test with both new and experienced users

Avoid

• Hiding essential functionality
• Requiring many clicks for common tasks
• Inconsistent disclosure patterns across the product
• Mystery meat navigation (unclear expand triggers)
• Over-hiding to the point of unfindability
