Disable list items

[Migrated From Jforum.net]

Hi,

I have a new problem.

I have a hierarchical list and i want to disable all children of a branch.

- fruit
 ---- apple
    ---- granny smith
    ---- golden delicious
 ---- orange
- vegetables

e.g. i want to disable fruit and all children of fruit.

Is there a way I can add ids to an array or list and then check if they exist to determine whether or not to display an item?

Liam
