Toggle Show HTML Nodelist elements with custom attribute

Question

I have an anchor elements with a custom attribute called "attachment_rename_link_no" (with the value being equal to a number) like so:

var attachment_rename_buttons = document.querySelectorAll("a[attachment_rename_link_no]")

The node list is appearing properly, however, when I do attachment_rename_buttons[0].style.display = 'none' , it doesn't hide the element.

Is there a special way to hide/show the display of nodelist elements?

UPDATE: Code works as expected
