Pro Tips for Undoing a Component in Figma

1. Use the Undo Shortcut
   Press Ctrl + Z (Windows) or Cmd + Z (Mac) to quickly reverse the last action, including component creation.

2. Right-Click to “Detach Instance”
   If you’ve placed a component and want to revert it to editable layers, right-click the instance and choose Detach Instance.

3. Rename Before Detaching
   If you plan to detach and edit a component, rename it first so you can track its changes easily.

4. Duplicate Before Editing
   If you might need the original component later, duplicate it before detaching to keep a clean copy.

5. Check Master Component Location
   If you accidentally deleted or altered a master component, find it via the Assets panel and restore it before making changes.

Common Pitfalls and How to Avoid Them

1. Deleting the Master Component by Mistake
   Removing the master component can break all linked instances. Always duplicate before making irreversible changes.

2. Confusing “Detach Instance” with Undo
   Detaching changes the nature of the layer, while Undo reverses recent steps. Use the right method based on your goal.

3. Editing an Instance Instead of the Master
   Changes made to an instance won’t update all components. Edit the main component if you want consistent changes.

4. Losing Overrides After Detaching
   Once you detach, any text or style overrides in that instance are lost. Save a copy if you want to preserve them.

5. Undo History Limitations
   Figma’s undo history is session-based—closing the file resets the history, so act quickly if you need to revert something.

Common FAQs About Undoing a Component in Figma

1. How do I undo making a component?
   Immediately press Ctrl + Z (Windows) or Cmd + Z (Mac) after creating it to revert it to individual layers.

2. What does “Detach Instance” do?
   It breaks the link between the instance and the master component, allowing full independent editing.

3. Can I restore a deleted master component?
   Yes, if it’s still in the file’s version history. Go to File → Show Version History to recover it.

4. Will detaching affect other instances?
   No, detaching only affects the selected instance, not the master component or other instances.

5. Can I re-link a detached instance?
   No, once detached, it cannot be re-linked automatically. You’d need to replace it with a fresh component instance.
