Hide buttons on list page after first record in that group

Will need more info to help...how about a screenshot of the list page with buttons?

Maybe you can slice the array like:

// Get top 1 record
$topRecords = array_slice($records, 0, 1);

foreach ($topRecords as $record) {
echo "<div>";
echo "{$record['name']}";
echo " <button>Edit</button> <button>Delete</button>";
echo "</div>";
}

// Show the rest without buttons
$restRecords = array_slice($records, 1);

foreach ($restRecords as $record) {
echo "<div>";
echo "{$record['name']}";
// No buttons
echo "</div>";
}

You will need to substitute the "Delete button" for your buttons.
