Conditional display of Active Areas

Asked by Steve Lee

Is it possible to conditionally display an active area? If a DB field is not NULL then display the active area. If the DB field is NULL then hide the active area? If this is possible could you show me a code example?

Thank you.

Yes, this is possible. You can add active areas using onBeforeEventRender where you can check if a specific property exists in the source data object (args.data):

onBeforeEventRender: args => {
  if (args.data.myField) {
    args.data.areas = [
      // ...
    ];
  }
}
