Drag Drop Problems

Identifying drag-and-drop accessibility barriers requires understanding the specific challenges faced by keyboard users, screen reader users, and users with motor disabilities.

## What You'll Learn

The specific accessibility barriers in drag-and-drop interactions and how to identify them.

## Why It Matters

You cannot fix what you cannot identify. Understanding the barriers helps you design inclusive alternatives.

## Real-World Use

A file upload area only accepts drag-and-drop. A user with a motor disability cannot precisely control a mouse to drag files. The upload fails. A file browser button would solve the problem.

## Common Barriers

| Barrier | Impact | Solution |
|---------|--------|----------|
| Mouse-only | Keyboard users cannot operate | Keyboard shortcuts + buttons |
| No focus indication | Users cannot track position | Visible focus on drag handles |
| No screen reader feedback | Users unaware of actions | aria-live announcements |
| Complex gestures | Motor disabilities blocked | Alternative click-based interaction |
| No undo | Users cannot recover from errors | Undo button or confirmation |
| Small targets | All users struggle | 44x44px minimum touch targets |

## Barrier Detection Checklist

```javascript
// Check for keyboard support
const draggable = document.querySelectorAll('[draggable="true"]');
const hasKeyboardAlternative = document.querySelector('.move-up, .move-down');

// Check for ARIA attributes
const hasAriaGrabbed = document.querySelectorAll('[aria-grabbed]');
const hasAriaDropEffect = document.querySelectorAll('[aria-dropeffect]');

// Check for live regions
const hasLiveRegion = document.querySelectorAll('[aria-live]');

Common Mistakes

1. Hidden drag handles

Drag handles that are too small or invisible are unusable.

2. No explicit move controls

Without up/down buttons or a move menu, keyboard users cannot reorder.

3. No drop zone indicators

Users cannot identify where items can be dropped.

4. Drop without confirmation

Destructive drops (deleting, moving) need confirmation.

5. No announcement of new position

Screen reader users do not know where the item landed.

Practice Questions

1. What is the most fundamental drag-drop accessibility barrier? Mouse-only interaction that cannot be performed with a keyboard.

2. What three ARIA attributes are relevant to drag-drop? aria-grabbed, aria-dropeffect, and aria-live for announcements.

3. What is the minimum size for a drag handle touch target? 44x44 pixels for touch targets.
