Open Source Document Management System | OpenKM

Hello there,

I'm trying to implement an if else statement for my metadata. But I'm having an error: Element type "if" must be declared.
How can I declare an element type?

Obviously will not going right. The tags available into the xml are based on rules set in the file http://www.openkm.com/dtd/property-groups-2.3.dtd ( any new tag there should be declared into new dtd description file and implemented into the openkm core to take effect.

In professional version we have parent-child feature between selects ( select parent value take effects among select child value ). The feature you propose for select input is not available neither profesional or community version and might be implemented ( I'm not sure if the place for setting this kind of logic is the xml file or extra layer in core for filtering fields, anyway seems be more near UI layer ).

Why do you need it, can you describe the scenario, because probably could solve it, doing with external form connected to openkm across api and build there your own logic.

Hello,

I wanna try if openkm can support an if...else statement that executes some code if a condition is true and another code if that condition is false.

Not possible without modifying the actual logic in the source code.
