Selectively enabling and disabling the choices of Listbox created by hiCreateListBoxField()

Manikk0501

Hi all,

              How can i selectively enabling and disabling a particular value in a listBox whichi created using hiCreateListBoxField().

For example,

              I have two listboxes and the value of listBox1 controls the choices in listBox2. I want to disable some of the choices of listBox2(greyed out) based on what i select in listBox1.  I can reshuffle the complete listBox2 through a callback from listBox1. Instead, I want just to disable the unwanted values in listbox2. How can i do it?

Thanks and Regards,

Manikandan Kuzandhaivelu

  • This is not possible. You cannot disable or enabled individual entries in a list box field.

  • i want to understand(advantage perhaps) why you want to grey out only those unwanted options of listbox2 instead of generating new set  of same, since each can only be triggered by the callback from listbox1. and greying out can only be done if the options are predetermined, (thus the need for the code to activate/deactivate each item, each time the value of listbox1 changes). BTW, graying out can be done by Radiobox but not by the listbox i think.
