Associative groups enable users to drag select items into correct categories.

The exact dragging functionality must be implemented with client-side scripts.

Each category starts with marker `@ ` and must contain one or more select items,
which start with marker `* ` and are indented beyond category marker.

Example:

```
@ Category 1

* one
* two
* three

@ Category 2

* five
* six

```
Associative groups enable users to drag select items into correct categories .
