Custom fields allows you to add (text fieds, date, pick-list, etc.) in your store.

Reminder!

Please read before making any changes. Customizing views gives you the power of changing any views in the Apps. It is like you are developing your own view. Therefore it is prone to errors and mistakes. Due to the fact that you are changing the original view, we cannot take the responsibility of your changes. We have made it as simple as possible and as robust as possible, however it is not bulletproof.

Here is the procedure for us to help you in case something goes wrong:
1. Every time you make a change you need to check that the view still works. Do not do 10 changes and then check. Because if something goes wrong you will not know what created the problem.
2. As soon as there is a problem, revert what you did.
3. If you need help, provide us with the step you did to arrive to your problem and we will be able to help you.
4. If you do not provide us with the step you did to arrive to the problem, we will not be able to extend our support to your issue. We can only help if we can reproduce your error on our test site following your step.
