README

Searchable ComboBox form control for Nette Framework backed by Nette\Database\Table\Selection.

Opens with the first N records on focus, filters via AJAX as the user types, and correctly pre-fills the label when opening an edit form – without an extra AJAX round-trip, even for a record deep in the dataset. Ships with built-in Bootstrap 5 and Tailwind CSS themes and full keyboard navigation.

composer require phloxcz/forms-combobox

Quickstart

1. Register the DI extension

# config/common.neon
extensions:
    combobox: Phlox\Forms\ComboBox\ComboBoxExtension

2. Include assets

<link rel="stylesheet" href="{$basePath}/vendor/phloxcz/forms-combobox/assets/combobox.css">
<script src="{$basePath}/vendor/phloxcz/forms-combobox/assets/combobox.js" defer></script>

3. Add the field to your form

use Phlox\Forms\ComboBox\ComboBoxInput;

$form->addComboBox('countryId', 'Country', $this->link('searchCountry!'))
     ->setSelection($this->db->table('countries'), 'id', 'name')
     ->setLimit(30)
     ->setTheme(ComboBoxInput::THEME_BOOTSTRAP);

4. Add a search signal to your presenter

public function handleSearchCountry(string $q = ''): void
{
    $this->sendJson($this['form']['countryId']->fetchData($q));
}

{label countryId /}
