Hide Empty Fields at Frontend? was created by Dave LeDev
How do I hide an empty field at the frontend? I tried using If empty at "Hide in item form" under Item form, but it won't work. I tried toggling to Both and it WILL hide the field in the backend but not the front.

Hello

it works like this

1. if the field has no value then no HTML display is created
-- unless you have custom layout that will create a "default display" or unless the field has been configured to use the default value of form for viewing too

2. Then the template file:
item.php
or
category_items.php

has field positions, that most of them will skip the field if display is NULL
in only a few template like (category) "blog" there are positions that will show the label even if field's display is empty

However I did note that this customization is not available for individual fields. Looking at the default code, it only checks if the label is set for display and outputs the value regardless. This is true for the tabbed template. Skimming through the code of other templates, I'm not finding a conditional that checks to see if the value is set or not. What's the conditional command to check if the value is set?

Hello

about fieldgroup field you found the setting

about individual fields, the code that --decides-- to show a field that has no HTML display
must be inside
the template files:

item.php
category_items.php

example
Code:
        <div class="flexi lineinfo subtitle1 group">             <?php foreach ($item->positions['subtitle1'] as $field) : ?>             <div class="flexi element field_<?php echo $field->name; ?>">                 <?php if ($field->label) : ?>                 <span class="flexi label field_<?php echo $field->name; ?>"><?php echo $field->label; ?></span>                 <?php endif; ?>                 <div class="flexi value field_<?php echo $field->name; ?>"><?php echo $field->display; ?></div>             </div>             <?php endforeach; ?>         </div>
After foreach add:
Code:
<?php if (!strlen($field->display)) continue; ?>
