Magento

Hi,
I’m a newbie in Magento, i’ve just installed my first version.

I have some products ex. hair extentions where there are variables on each type:

-wifted_type
--Brown_color
--- 22” lenght
--- 34” lenght
--Black_color
--- 12” lenght
--- 22” lenght
--- 32” lenght
--- 42” lenght

-Glued_type
--Blue_color
--- 12” lenght
--- 36” lenght
--Black_color
--- 12” lenght
--- 32” lenght
--- 42” lenght

First the user select type
then a color there are for that type
and then lenght there are for that color

Can I do like this in Magento?

You can achieve this with configurable products.
