How to hide a tab_area on loading a form

Question

Hi
I think that my situation is a bit different to this. https://www.chronoengine.com/forums/posts/f5/t99095/hide-or-show-containers-of-type-tab.html

I need to be able to hide a tab when there is no data for that tab.

In this example, there is data for the member but not for the partner. Once the form loads I decide if there is or is not a partner. I can then prevent the content appearing in the partner tab but need to hide that partner tab (ideally) or at least set the tab label to be empty. I presumed that I could use some javascript and DOM code to hide the tab. But the tag id is not easy to deduce. It doesn't seem to be to be related to the tab id other than the <a> tag in <ul><list> tag.

any suggestions greatly appreciated.

Regards

Nick

That does it Bob but with a slightly different approach.

I set a Load CSS on the form load and in there made the second tab not visible

form#chronoform-bookingCourseOnLine  
div.chronoform-container li:nth-child(2){
display:none;
}

Then I set up an event switcher with two events - 'member' and 'partner'. In the code I detected whether the partner exists and based on that return 'partner' or nowt.

<?php
  if (isset($form->data['currentUserAndBookings']->Partner)) {
return 'partner';
}

?>

Finally in the 'partner' event I made the tab visible again.

form#chronoform-bookingCourseOnLine  
div.chronoform-container li:nth-child(2){
  display: block;
}

Bingo! Just what I wanted.

Thanks for the help
