I think the category feature of eBay is very handy. I want to figure out
a way to to make this function work on rails.
What is so sepcial with ebay’s category feature?
Let’s say we are going to buy a Movie DVD.
HOME->BUY->DVDs & Movies
in ‘Categories within DVDs & Movies’, click the first item ‘DVD, HD DVD
& Blu-ray’. ok, now its fancy categories for dvd movie is ready, right
on the left sidebar.
isn’t it different?
- It has multiple category systems: movies are divided by their Format,
Genre(with subgenres), Rating and Condition. - This multiple category systems are interactive. If you go deep to one
category system’s subcategory, for instance we click PG-13(under Rating
category), the other category system stay on sidebar, only now all
categories show movies that is rated PG-13. (if any category doesn’t
have any movies rated PG-13, this category removed) - A number is shown besides every category name to indicate how many
movies’ are below this category.
This is a very useful system to help you pick out the very few movies
that you love from more than 200,000 choices…
Is it hard to do it on Rails?
