DaData Lite

What this solution does

DaData Lite is a module for the 1C-Bitrix platform that provides DaData autocomplete and suggestions for website form fields. The tool speeds up and simplifies data entry by automatically proposing correct options as users type.

The module supports autocomplete for the following data categories:

Full Name — search and selection of last name, first name, and patronymic;

Address — generation of suggestions based on address structure;

Organization / TIN — search for legal entities and retrieval of data by TIN;

Bank — search for banking institutions;

Email — suggestions when entering an email address.

Phone number normalization is also available via the DaData API.

Key features of the solution:

Rapid integration with existing website fields.

Binding configuration management via the 1C-Bitrix administrative panel.

Operation in multisite configurations with support for multiple domains.

Flexible configuration of the CSS selector, suggestion type, result limit, and request delay.

Server-side interaction with the DaData API, preventing access keys from being transmitted to the client browser.

Response caching to reduce load on the DaData API during repeated requests.

Adaptive design for the suggestion dropdown list.

Support for keyboard navigation.

The module allows placing multiple suggestion blocks on a single page.

Installation requires no modifications to init.php or the 1C-Bitrix core files.

Use cases

DaData Lite is suitable for registration forms, order forms, feedback forms, delivery forms, contact forms, and other site fields where users must enter addresses, full names, organization names, tax identification numbers (INN), banks, or email addresses. Operation requires a valid DaData API token with an available request quota. The module functions via the DaData API and does not include the service's own tariffs or usage limits.

When needed, General iT can implement “DaData Lite”, configure the module and verify it against the current website setup.
