In this article, you will learn how to undo an action. For instance, I will change the background color of a paragraph element.
If I decide that I don't like that, I can click on the undo button and it will undo that action.
Now, if I were to change the background of the paragraph element again and then lock the item by clicking on the Lock Item feature under Positioning in the left sidebar, I will not be able to undo the change that I made to the paragraph element. I would first have to unlock that item and then I'd be able to undo the change.
And that is how you use the undo button inside of the Designrr editor.
