In Hilchos Chanukah there is one halacha that is different from all other halachos.
This halacha has no mekor in chazal , the first mekor is from Eliyahu Hanavi.
What Halacha is this?
The Chida writes that the Chesed L’avraham (nehar 58 mayan 2) found a
ksav yad kodesh and copied from there, this halacha.
There are only 15 materials that a menorah may be made of.
It also has to stand on its own without leaning on something,
He holds that you need a keli to light the Chanukah
licht. You may not place candles on the floor or wall and light. You must
have a menorah or cups to place the candles in. You also may not
use a onion or a potato to place the oil or candle in it.(it is not considered a keli)”
