How to Use Undo / Redo in the Builder
Made a mistake? No problem. MobiDrag's App Builder tracks every change you make so you can step backwards or forwards through your editing history at any time.
1 Where the undo & redo buttons are
The undo and redo buttons are in the center of the builder sub-toolbar — the narrow bar just below the top navigation, to the right of the page selector dropdown.
| Button | Icon | What it does |
|---|---|---|
| Undo | ↺ left-pointing arrow | Reverses your most recent change |
| Redo | ↻ right-pointing arrow | Re-applies the change you just undid |
2 How to use undo and redo
Click the undo arrow once to step back one action. Click it again to step back another action. Each click reverses one discrete change.
After undoing, the redo arrow becomes active. Click it to re-apply the change you reversed.
- 1Make a change — drag a block, edit text, adjust settings, or delete a block.
- 2If the result is not what you wanted, click the ↺ undo arrow in the toolbar.
- 3The canvas reverts to the state before your last action.
- 4If you went too far back, click the ↻ redo arrow to move forward again.
3 Keyboard shortcuts
| Action | Windows / Linux | Mac |
|---|---|---|
| Undo | Ctrl + Z | Cmd + Z |
| Redo | Ctrl + Y | Cmd + Shift + Z |
Keyboard shortcuts are the fastest way to undo. Hold Ctrl + Z to step back through multiple actions rapidly.
4 What changes are tracked
The undo history tracks every edit you make within a builder session:
- Adding or removing a block from the canvas
- Reordering blocks (drag to new position)
- Changing any setting in the right panel (color, text, toggle, slider)
- Duplicating a block
- Switching blocks on and off (visibility toggles)
5 Limits and things to know
| Scenario | Behavior |
|---|---|
| Undo after saving | Undo still works within the same session after a save. The save just creates a version snapshot — it does not clear the history. |
| Undo after page refresh | History is cleared on page reload. Save your work before refreshing. |
| Switching pages | Each page has its own history. Undoing on the Home page does not affect edits on the Products page. |
| Brand Kit changes | Changes made in Brand Kit mode have their own separate undo history. |
Good practice: Click Save frequently as you work. This creates version snapshots, giving you both undo (within session) and the ability to reload a saved state if needed.
