Wish list, gift list or group gift
One choice is fixed
The first step of a new list asks who it is for. That decides what the list can do, and it is the only thing you cannot change later. Name, occasion and who sees it can always be changed.

For myself: a wish list
What you would like. Share it and others can tick what they are buying, and you see neither what nor who. That keeps the surprise. If you would rather know, switch it on for that list.
For someone else: a gift list
Ideas for someone who never opens the list themselves. Whoever you share it with ticks what they are buying, so nobody buys twice. You do see that, because you are giving too.
Together, for someone: a group gift
One gift, several givers. Everyone with the link can add ideas, vote on them and say what they will chip in. No money moves here; you settle that between you. More under Buying a gift together.
An occasion and a date
Any list can carry an occasion: a birthday, Christmas, a wedding, a birth, and ten more. For a birthday, Christmas and Valentine the date fills itself in. With a date, you get a reminder in time.
