Two Problems

1) If you notice in JSFiddle, we get keys and values in the drop-down. We only need keys i.e. we only need All, Dept one, Dept two and so on in the drop-down.

2) Since I already have a data-inbuilt “All” option, how do I remove the promptText value from the drop-down?

    1. It’s a little buried in the documentation but the root example shows how you can use .title() to set the option text, like so:

      .title(kv => kv.key)

    2. That first element seems to be hard-coded in there, so I’d listen to the pretransition event and use an attribute selector to choose the option with the blank value and remove it:

      selbox.on('pretransition', function() {
  selbox.select('option[value=""]').remove();
})
.filter("Dept 1")

    Note: you may run into other charts not adding up correctly if your rows aren’t completely distinct.

    For posterity, the above answer didn’t work for me using CboxMenu, but this did:

    cbox.filter("Dept 1")
.on('pretransition', function() {
  cbox.selectAll('li:not(.dc-cbox-item)').remove();
})
