What are categories?
Categories define the profile of a competitor participating in the event. They are created based on criteria such as gender, age, weight and skill level (belt). Categories are a fundamental element when creating an event.
In order to open the categories management page:
- Go to the admin panel and click Manage events.
- Open your event page.
- In the top menu Competitors choose List of categories.
- Click Manage categories.
I. How to use the interface for managing categories?
The interface contains a few buttons.
General options
If the event does not contain any categories, buttons will be:

- Import from template — allows choosing a predefined set of categories and load it into the event and customize to your needs.

After clicking the Customize template option, a window with categories to import will appear:

- Import categories from a previous event — if you organized at least one event before, you can use the same set of categories as previously.
- Start creating categories — it creates the root for all categories and lets you extend it.
II. How categories are built?
Tree root
The root of the categories tree is the starting point from which you begin adding categories by branching each element in the tree.
The name of the root element can be anything. It's not going to be visible on the categories listing available for competitors.
Example
Example categories below:
adult;white;-70 kg
adult;white;-76 kg
adult;white;-82.3 kg
adult;blue;-70 kg
junior;-84 kg
...
They are stored in the following tree structure:
- "tree root"
- adult
- white
- -70 kg
- -76 kg
- -82.3 kg
- blue
- -70 kg
- white
- junior
- -84 kg
- adult
Options for elements in tree
Each element in the tree contains a few buttons once the mouse pointer is moved over. They can be:

Buttons are responsible for:
- Edit name. If you click it, you will be prompted to provide a new name for the category.
- Change settings. It allows you to adjust certain settings for a specific category. See next paragraph.
- Extend category. It allows you to create sub-categories for the selected category. For example: having structure
adult -> blue, we can extendblueby weight classes. - Move category. Here you can move the category to a different place in the category tree. First you select the category node you want to move, then you need to confirm the new place that node should be moved to.
- Delete. It deletes the category if there are no existing competitor registrations.
Adding new elements
Each level of the tree contains a button Add:

It allows you to add a new category on the selected level of the tree. Once you click it, you'll be prompted to provide a name for the new category. Click OK then.
Sorting elements
All elements in the tree can be sorted by using the mouse cursor.
You just need to click the selected element, hold the mouse button and move it up or down.

III. Category settings

Each element of the tree can have certain parameters adjusted. They are:
- time of fight
- scoreboard
- gender restrictions
- age restrictions
Setting these parameters automatically makes all sub-categories inherit these settings. Thanks to that, you don't have to set the scoreboard, for example, for each category in your event, it's enough to change it only for the root.
Inheritance example
The image below presents the following properties of the categories tree:
- root
eventmakes all categories use BJJ scoreboard (monitor/TV icon), - category
adultand all nested categories are limited to male gender (icon) and it's only possible to register competitors +18 (calendar icon),- nested categories have different times of fight
- scoreboard is deduced automatically based on root category
- category
juniordoes not have gender restriction, but age restriction is 16 years old (inclusive) up to 17 years old (inclusive) + fight time for each weight class is 5 minutes.
