When creating a tender there is a section for custom options.
These can be added 1 by 1 as required however if the option is a build up of items like a package and there are several of these required then the custom build up functionality should be used.
Custom Option = Outdoor Kitchen
Qty = 2 Outdoor Kitchens
To start, go to the tender edit screen and create the custom option (package) as 'Outdoor Kitchen'.
Once this has been created click on 'Convert to build up...' in pane 3
In the new table that has opened up in pane 3 create your build up for the outdoor kitchen items;
Once you have finished you can modify the total price by entering an override value (if you have permission to do so) otherwise you can leave the total value as is.
