Material Categories

Categories let you organise your materials into groups — for example, “Filters”, “Electrical components”, “Refrigerants”, or whatever fits your inventory. Once set up, you can filter the materials list by category to find what you’re looking for quickly.

Categories can be nested. You could have a top-level “Filters” category with subcategories “Air filters”, “Oil filters”, and “Water filters” underneath. There’s no limit on depth.

When filtering the materials list by a category, materials in any of its subcategories are included automatically.

Each category can be marked active or inactive. A category is only fully active if it and all of its parent categories are active. If a parent category is inactive, its subcategories are effectively inactive too, regardless of their own setting.

Inactive categories are not shown to users when assigning categories to materials. If a category disappears from the selection options, check whether a parent category has been deactivated.

Go to Materials → Categories to see the full category tree.

Click Add category and fill in:

  • Name — the category name
  • Description — optional, for internal reference
  • Parent category — select a parent to nest this category, or leave blank for a top-level category
  • Active — whether this category is available for use

Open any category from the list to edit its name, description, parent, or active status.

Moving a category to a different parent repositions it (and its subcategories) in the tree.

Delete from the category’s edit page. Deleting a category removes it and all of its subcategories. Material records that were assigned to the deleted category lose that assignment.

Categories are assigned on the material record itself. When creating or editing a material, select one or more categories from the category picker. Only active categories (with all active ancestors) are shown.

A material can belong to multiple categories at the same time.
