    I need to join three selects. Each depends of the parent select. How can i make it with Meta box?

    Hi,

    This is very specific, so I think the only way to do that is via custom JavaScript.

    • You listen on "change" event of the parent select
    • Get the options' values you want to combine from 3 selects
    • Update the list of options of a select field.

    Without custom JavaScript, I can't think about another solution.
