CB Conditional documentation

Is there any documentation on how to implement the CB Conditional plugin? I've enabled it but I don't know how to get my registration page to work with tabs.

There is no documentation for incubator projects, they're a learn as you go experience. To enable step by step registration you'll need to navigate to CB Conditional in plugin management and enable it from CB Conditional configuration. Ensure you have DIV layout set within CB configuration on the user profile tab or you will not be able to use step by step.

Thanks, I've changed the layout and it's working now.

Another question: if i create a checkbox field to use as a conditional to several other fields in the tab, what should be the operator and valeu condition to hide all fields if the checkbox isn't checked?

Is it a single checkbox? If so then you've 1 = Yes and 0 = No, so your values would be 1 or 0 based on need. You'd use whatever operator fits the scenario (e.g. Equal To).
