disable selection in primefaces picklist

Question

Is there a way to disable the move buttons and drag n drop based on condition? I want to disable the move\select from source to target(or vice versa) in case the target contains 3 item?

Is it possible? I couldn't find any answer.

Answer 1

You can try with disabled attribute of picklist, which disables the whole picklist. You can pass call a backing bean attribute which returns a boolean value calculated according to your condition.

On your view

disabled="#{backingBean.targetHasThreeItems}"

and on backing bean

 public boolean targetHasTreeItems() {
    // here your code that calculates target item's count
   }
