@pionect– We implemented in the next beta, which will hopefully be released this week.
Format will be:
,'choices' => array(
'Group 1' => array(
'first' => __('First Choice', 'piklist-demo')
,'second' => __('Second Choice', 'piklist-demo')
,'third' => __('Third Choice', 'piklist-demo')
)
,'Group 2' => array(
'first' => __('First Choice', 'piklist-demo')
,'second' => __('Second Choice', 'piklist-demo')
,'third' => __('Third Choice', 'piklist-demo')
)
)
