Hi All,
I have a set of categories. Some categories have sub-categories. All - categories and sub-categories are the same class - Category.
Can I list all the categories in a form like this:
[] category1
[] category2
--[] sub-category21
--[] sub-category22
[] category3
--[] sub-category31
.
.
I was unable to render this via CheckboxsetField and I cannot figure out other way to realise this.

Thanks

P.S. sorry for my english
