I have a form of contributions with some options:
5 first options based on multiple product with a fixed amount, and another option is based on the single product.
I want only one of the two options will be mandatory
How can I make mandatory field will be one of the options of "multiple product" or the option of a "single product"?


Thanks!

You can achieve this using the Payment package's 'Donation' and 'Multiple products' fields, as well as the 'Conditional fields' feature:

- Please add a multiple product field to the form and set one of it's items as follows:

0|Specify a donation amount

When selecting this item, no value will be added to the total, as the item's value is set to '0'.

Then, please add a 'Donation' field to the form. Head to it's 'Validations' tab and set 'Required' to 'Yes'.

- Head to Components >> RSForm!Pro >> Manage Forms >> edit your form >> Properties >> scroll down to 'Conditional Fields' and click on 'New Condition'. You will need to create a condition that will only display the 'Donation' field if the 'Specify a donation amount' option is selected within the multiple product field.
