A custom cake order form with calculations

A simple cake order form that calculates the total price of the cake based on the options chosen
This cake order form can calculate the total cake price based on the options selected by the customer. In the form, select the options for example, the size of the cake or the filling. Notice that the total price changes as you choose the options. This is an example of how to build order forms with custom calculations. The code uses NittiJS for calculations. As you can see in the sample code, you only have to provide the formula for the calculation in the r-calc attribute to get the calculation working. NittiJS can also show/hide a part of the form conditionally. When you select the option for inscription, the textbox to enter the inscription is displayed. This is done using r-show attribute in the container div See NittiJS documentation ( ) for usage instructions.
