We use comparative adjectives between two things. Why in this sentence we use "other than the others? Isn't that tree bigger than the others? Do we say "my brother is shorter than me or I"? She is taller than her friend (is) can "is" be used here or not?
Technically, because "than" is a conjunction, it should be followed by a clause. So, it is preferred by many to use "I" in "my brother is shorter than I". It is an ellipsis of "my brother is taller than I am". In informal English, many people use "me". That turns "than" into a preposition, which is considered a usage problem by careful speakers and writers.
Yes, you can use "is" after "her friend".
