Hi guys
I want to know if it's possible to enable/disable a metadata field based on another metadata field in the form?
For example, when the user is filling the metadata form, if he selects a checkbox filed, another metadata field of the form becomes disable dynamically
I read about metadata validator elements but my requirements do not satisfy with that.
Is this possible at all and if yes, how?
Thanks in advance

No, should be modified the source code for this kind of behaviour ( not trial I must advice ). In this scenario maybe is better to create your own form as a customization in a new tab like https://docs.openkm.com/kcenter/view/ok ... nsion.html
