Accessories can be used in a smart way. Under the tab "accessories" in an equipment item (item, case or kit) you can add items from your database as accessories and edit three further yes/no options: automatic, skip, free.
Automatic: If you put "no" here and you plan this item in a project, a pop up window will appear and ask for your confirmation if the accessories should or should not be added. This could be useful for microphones or rain covers, that are added regularly but not always.
Skip: If you put "skip = Yes" accessories will only be added once even if the item itself is added with a higher quantity. This could be useful for example if you add a truss with the accessory "hammer". The hammer will only be added once no matter how many truss you actually add.
Free: If you put "free = yes", the accessories will be added without any additional money charged. This could be used for example for cables that are delivered for free when rented with a certain item but can also be rented separately with an own price.
