Recommend me a camera tripod that will fit in a small rucksack, and will also extend to full size

[Ricochet J]

Hi,

My wife takes her camera (Fujifilm xt-20) with her everywhere.

She doesn't have a tripod and I want to get her a portable travel tripod.

Recommend me a camera tripod that will fit in a small rucksack, is light weight, and will also extend to full size.

I'm a complete newbie - Amazon seems like a minefield.

Can you help? Thank you
