I deleted a component from many elements

Question

I've deleted the answer component of all my elements in attempting to format the creation of a new element

How Do I Fix/Retrieve them?

(The question component is all that remains of my elements and is now located on the bottom of my element window. The question component appears to be in the associated folder.)

Suggestion

As there are not options for deleting components from many elements, you probably only deleted the component from the template You could then recreate the tempate and apply it to the deficient elements
