I have a select input that's pulling it's options from one of our site's vocabularies. I'd like, however, to alter the options to include a data attribute based upon a custom field within the term.
The input looks like:
$form['my_sample'] = [ '#type' => 'webform_term_select', '#title' => t('Sample Reason'), '#vocabulary' => 'sample_reasons', '#tree_delimiter' => '- ', '#empty_option' => t('Make A Selection'), '#select1' => TRUE, ];
I tried hook_webform_options_alter(), but that wasn't the right approach.
How do I alter/add to the select options in this scenario?
