Freeze the location of a text box, while still allowing customers to change the text. Customers will be able to replace, delete and change the text style, size, etc. but won’t be able to move the location of the text box.
Highlight the text box you want to freeze, then right-click and select Freeze > Frozen. Customers won’t be able to unfreeze frozen text boxes . If you want an image on the artboard to stay in place (not move around), but still be replaceable by customers, you can freeze it (right-click > Freeze> Frozen).
Do not lock or hide the image layer, as your customers won’t be able to select and replace it, if done so.
