A more thorough explanation:

Term: ad libitum
Definition: Ad libitum means "at pleasure." It is a Latin term that is often used in legal contexts to indicate that something can be done as one pleases. For example, in a court case where damages are uncertain, the amount of compensation may be left to the discretion of a jury, who can assess it ad libitum.
Examples: A musician may be asked to play a solo ad libitum, which means they can improvise and play whatever they want. Similarly, a chef may be asked to add spices ad libitum, which means they can add as much or as little as they want to a dish. In both cases, the performer has the freedom to do as they please, within certain limits. These examples illustrate how ad libitum can be used to give someone creative freedom or flexibility in their work.
