Topic: Tree like view+item add/removal
I have to implement a list of categories+subcategories and give the user the possibility to add or remove items. I thought that a tree like system would look nice, with Categories items deploying/hiding its subcategories with a click on an icon, and also provide the chance to modify/remove the category/subcategory, or add a new one. As you can see, a quite complex mess for a newbie. Any suggestions about how can I do this, or any other better way to do it?
