What's the best way to deal with tree structures? Use the following setup in a database as an example: ID | Parent | Description ------------------------

1 |        |   Colours
2 |    1   |  Red
3 |        |   Hello
4 |    1   |  Green
5 |     4  |  Light
6 |     4  |  Dark

This should be represented as: 1. Colours 4. +--Green

6.       +--Dark
5.       +--Light

2. +--Red 3. Hello (ie, in tree structure and ordered alphabetically by 'descriptiu What's the best way to select the data and render it in HTML?
