Hi sabrinazeiden,
You’re absolutely right about using the select2_args filter – that’s the correct approach since Taxonomy fields use Select2 but don’t expose the “Stylized UI” option. Here’s the JavaScript that will remove the search box:
javascript
acf.add_filter(‘select2_args’, function(args, $select, settings) {
// Check if this is a taxonomy field
if (settings.field_type === ‘taxonomy’) {
// Remove the search functionality
args.minimumResultsForSearch = -1;
}
return args;
});
Alternative approach – if you want to target specific taxonomy fields by their key or name:
javascript
acf.add_filter(‘select2_args’, function(args, $select, settings) {
// Target by field key
if (settings.field_key === ‘field_1234567890abc’) {
args.minimumResultsForSearch = -1;
}
// OR target by field name
if (settings.field_name === ‘your_taxonomy_field_name’) {
args.minimumResultsForSearch = -1;
}
return args;
});
Where to add this code:
In your theme’s JavaScript file that loads in admin
Or in the ACF admin footer using this PHP:
php
add_action(‘acf/input/admin_footer’, function() {
?>
<script>
acf.add_filter(‘select2_args’, function(args, $select, settings) {
if (settings.field_type === ‘taxonomy’) {
args.minimumResultsForSearch = -1;
}
return args;
});
</script>
<?php
});
The minimumResultsForSearch = -1 trick tells Select2 to never show the search box, regardless of how many options there are. This is much cleaner than trying to hide it with CSS.
This should completely remove the search dropdown from your Taxonomy select fields while keeping the regular Select fields unaffected.
