# FromCategory

The ID of one or more categories to use to train the specified category. IDOL Category Component uses these categories and all their training to train your category. Separate multiple category IDs with commas. There must be no space before or after a comma.

As well as allowing you to include categories alongside other training (such as text) for your category, using `FromCategory` allows you to combine multiple categories in one.

NOTE: If you also train the category with a Boolean expression or text, IDOL Category Component uses the Boolean expression or text that you specify in preference to any text or Boolean training from the source category.
