NovaMind 5 has a unique and powerful checkbox system.
You can show checkboxes on the topics of your Mind Map. Just select the topics you want checkboxes added to, and click the Format/Checkbox button. All checkboxes are three state checkboxes, meaning that they can be checked, unchecked, or in an indeterminate state, which is used to show that a task is partially done.
There are two types of checkboxes: Automatic and Manual checkboxes. By default, all checkboxes are automatic. Automatic checkboxes get their checked state by accumulating the state of the checkboxes on their subtopics. Manual checkboxes are completely independent of their subtopics. Automatic checkboxes are square, and manual checkboxes are round.
While it is possible to mix automatic and manual checkboxes, in most cases, it is best to stick with one type, especially within one subtree.
When you are using the default automatic checkboxes, when you alter the checked state of a parent topic, it will affect its subtopics.
If you collapse subtopics, the parent topic will still show the checked state of all the subtopics.
If you have a gap in the hierarchy of checkboxes, then the inheritance of automatic checkbox state is broken, so if you have a parent with an automatic checkbox on it, no checkbox on the selected topic, and checkboxes on the subtopics, then the checkbox on the parent will not be affected by the state of the children, and nor will changing its checked state affect the subtopics.
