A method truncates text entered via a text box user interface element. The method includes displaying a user interface on a display device of a client computing device, where the user interface includes first and second text entry fields within a collapsible text entry box. The method further includes receiving a first stream of characters into the first text entry field, initially displaying all characters of the first stream as the first text entry field receives the first stream, truncating the displayed characters of the first stream, resolving the truncated displayed characters of the first stream to a first object displayed within the collapsible text entry box, receiving a second stream of characters into the second text entry field, and further truncating the displayed characters of the first stream while receiving the second stream of characters into the second text entry field.
