Custom field with two drop-down menus

I assume you already had a look in the related docs article?

Hence the part about multiple inputs in one field:

"... Please, pay special attention on input name. In order to get your field values saved the form alements have to have name starts with fields[<?php echo $this->id; ?>]. If you need more than one input as part of one field make it array fields[<?php echo $this->id; ?>][] or array with exact keys fields[<?php echo $this->id; ?>][name] ..."

Apart from that, have a look at existing Cobalt fields that may have a similarity in form input(s).

( I guess, Sergey will chip in here with valuable infos for you... )

hello

I've solved it, I used wrong functions for store multiple data.

tnx, Peter

I hope we will see this field in depot very soon :))

I am excited.
