9. Validation Rules: This is usually used for Text custom field type, and it will be generated automatically when users select Data Type Validation of the field (mentioned above). The extension uses JQuery Validation Engine to validate data users enter on subscription form, so if you want to take full advantage of this validation engine, please read the documentation at http://posabsolute.github.io/jQuery-Validation-Engine/ to see all powerful validation rules which you can use to validate data of the custom fields.

Understand "Display In" property

When you add/edit custom field, there is an important property called Display In. It controls on what form/what step in the registration process the custom field will be displayed. If you use shopping cart feature, you don't have to worry about this property (just set it to ALL - default value). However, if you use Individual/ Group Registration option, you should understand the meaning of all the options of this property:

1. ALL: This custom field will be displayed on all registration steps.
2. Individual Registration Billing Form: This custom field will only be displayed on Individual Registration form (when registrants click on Register (Individual) button)
3. Group Billing: This custom field will only be displayed on Billing Information step in group registration.
4. Both Individual and Group Registration Billing Form: This custom field will be displayed on Individual Registration Form and on Billing Information step in group registration.
5. Group Member Form: This custom field will only be displayed on Members information step on group registration to allow collecting group members data.
6. Both Group Member form and Individual Billing Form: This custom field will be displayed on Individual Registration Form and on Members information step on group registration.

Dependency settings (Conditional Custom Fields)

Sometime, you want that when registrants select certain otpions (From List, Checkboxes, Radio custom fields), there will be additional fields be showed/hided to allow entering additional information. If that's the case, you will need to use this Conditional Custom Fields feature

1. Depend On Field: Select the field (which we call master field) this custom field will be depended on. In this dropdown, the system will display the published List, Checkboxes, Radio custom fields which you created in the system. When you select a field from this dropdown, the custom field which is being added/edited will only be displayed if certain values of the master field is checked/selected.
2. Depend On Options: Check on the options which you want this field to be showed when subscribers select an option from master field.

To make it easier for you to understand the concent, let's take an example. On registration form, you have:

1. A checkbox custom field called Programming Languages which allow subscribers to choose the programming language they can use. It has 3 values: PHP, HTML, CSS
2. You want that when registrants selects a programming language, there will be an additional text field to collect more information (version of the programming language - it is not a good example) about the programming languges he can use. In this case, you will create 3 additional text fields:
   • PHP Version: For this field, you set Depend On Field to Programming Languages. And in the depend on options, you select PHP
   • HTML Version: For this field, you set Depend On Field to Programming Languages. And in the depend on options, you select HTML
   • CSS Version: For this field, you set Depend On Field to Programming Languages. And in the depend on options, you select CSS
3. Now, when registrants access to registration form:
   • If they check on PHP checkbox, the PHP Version field will be showed. If they uncheck this option, the field will be hided.
   • If they check on HTML checkbox, the HTML Version field will be showed. If they uncheck this option, the field will be hided.
   • If they check on CSS checkbox, the CSS Version field will be showed. If they uncheck this option, the field will be hided.

Please see the screenshots below to understand the setup and hopefully, you get the idea about how it works and can use conditional custom fields feature in Events Booking now. If not, post a question on forum and I will be happy to answer or help you with a sample setup for your system:
