Thanks a lot.

I know this is old, how can I get the first value of the repeater.

Im using this reapeater with 1 text field, I need to grab the first item of that array.

Any chance for the help!!

@rozuja Don't think you need any more, but it might help someone in the future:

You can get the values by calling vc_param_group_parse_atts([the param_group]) function.
for example if you have a param_group with param_name titles, use:

$titles = vc_param_group_parse_atts( $atts['titles'] );

$titles[0]; // will return the first title in that list

Is htere a way to pass values to label and excerpt on start for multiple fields? So to have multiple fields visible on start with predefined values?
