I'm trying to popup a window with a list of strings that I can then individually select and copy to the clipboard. Using CreateDialog I can select items formatted as a Quantity but not simple text. In the example below I can right click and copy the 1kg entry, but not the Hello text. I tried a few Copyable/Selectable options with no luck. Is there a way to make the text selectable in a CreateDialog?
CreateDialog[{"Hello", Quantity[1, "Kilograms"]}, ContentSelectable -> True, Copyable -> True, Selectable -> True];


Quantityhas both a tooltip and specially defined right-click behavior, and the dialog doesn't suppress that. – Jason B. May 09 '19 at 20:04
