Why can't I select or delete an element in the Wix Editor?
Often, an element will be placed behind or in front of another element. Because of this, you might have difficulty selecting or deleting a specific element. You can solve this by bringing the element forward.
To bring an element forward: Click the element > from the pop-up menu, click the Bring forward icon. You will, then, be able to move, edit or delete the element.
Alternately, if you are unable to click the element to select it, click the element in front of it > click the Send backward icon to send that element behind the element that you are trying to access.
For an element in your header, when unchecking the Show on all pages box, the element might move behind the header causing it to appear inaccessible. To access the element, move the header backwards as described above or use Ctrl + M to toggle through the elements on your page until the element is selected.
