Tree catalog from Highload block

MODULE FOR 1C-BITRIX

Xlogic

Tree catalog from Highload block

The xlogic.hlfield module introduces a new user-defined field type and infoblock property called 'Tree Directory (Highloadblock)'. Instead of a standard dropdown list (Select), the tool provides a full hierarchical tree of unlimited depth. Data is stored in Highload-blocks, ensuring high performance and configuration flexibility.

What this solution does

The xlogic.hlfield module introduces a new user-defined field type and infoblock property called 'Tree Directory (Highloadblock)'. Instead of a standard dropdown list (Select), the tool provides a full hierarchical tree of unlimited depth. Data is stored in Highload-blocks, ensuring high performance and configuration flexibility.

This solution is suitable for product or service categories, rubrics, and sub-rubrics; geographic directories (Country → Region → City → District); and hierarchical classifiers (OKVED, job types, positions).

The module supports deep trees with unlimited nesting, where the actual level depends only on settings. Flexible selection modes are available: users can restrict selection to only leaf elements (final items), only root nodes, or any node in the tree. The 'Maximum Depth' setting allows control over available selection levels. An embedded filter line above the list enables fast search by name. Filtering of directory records by the activity field UF_ACTIVE is also supported.

The tree directory module based on a Highload block automatically updates the list of available fields (parent, name, sorting) when a block is selected. The system performs validation by verifying that the selected value exists and meets specified criteria, including depth and node type.

General iT can take care of implementing “Tree catalog from Highload block”, including installation, configuration and result verification.

UPDATE HISTORY

What’s new

1 releases
1.2.0 (17.10.2026)Latest update

Saved field values no longer disappear when catalog records are deactivated, and value validation now matches what the editor sees in the list.

Fixes

If a catalog record has been deactivated, a previously selected value is no longer reset upon saving the item: it remains in the list marked as "(inactive)" and is saved as is. On the site and in the admin list, the name of such a record is displayed instead of its ID.

Values that can no longer be selected (the record has been deleted, it has no parent, it is deeper than the maximum depth, or it does not match the selection mode) are also visible in the list, marked as "(unavailable for selection)" or "[ID] (not in catalog)". Previously, such values were silently erased upon form submission.

Validation upon saving, including during import and saving via API, now accounts for maximum depth and does not allow records that lack a parent.

The "Leaves only" mode combined with depth restriction: leaves are considered items at the last displayed level. Previously, the list in this case could have been empty.

The property validation error for an infoblock was previously displayed as "Array". Now, the message includes the property name and the ID of the invalid value.

If a field setting specifies a field that does not exist in the Highload block, the edit form no longer terminates with an error: the value list is empty, and a clear message is displayed upon saving.

Filtering by a user field in the admin list preserves the selected record, even if it is inactive.

In the field settings, the names of the Highload block field codes are displayed next to the codes in the interface language.

The module settings page is accessible only to users with access rights to the module.

Compatibility

If an item has a saved value marked as "(unavailable for selection)" or "(not in catalog)", the item will not be saved until another value is selected or the previous field settings are restored. This is done to prevent values from being lost unnoticed.

The internal structure of the module has been redesigned. Field settings, saved values, and event handlers remain unchanged. Direct calls to the module from site customizations continue to work.

Search scripts and field settings have been updated. If an old script remains in the browser, refresh the page with the cache cleared.
