# Advanced Layout Builder Tabs

Provides a **Layout Builder** section layout where you define the number of tabs
(1–10) and their labels. Each tab is its own Layout Builder region, so you can
place **multiple blocks per tab** — not just one block per tab like the
`layout_builder_tabs` module.

## Requirements

- Drupal 10 or 11
- `layout_discovery` (Drupal core)
- `layout_builder` (Drupal core, for the Layout Builder UI)

No contrib module dependencies.

## Installation

1. Copy the `adv_lb_tabs` folder into your `modules/contrib/`
(or `modules/custom/`) directory.
2. Enable the module: `drush en adv_lb_tabs`
3. Go to a content type's **Manage Display** → **Layout Builder**, add a new
section, and choose **"Advanced Layout Builder Tabs"** from the **Tabs** category.

## Usage

1. Click **+ Add section** in the Layout Builder.
2. Select **Advanced Layout Builder Tabs** from the **Tabs** category.
3. Set the **number of tabs** (1–10) and a **label for each tab**.
4. Save the section. Each tab appears as a labelled drop zone.
5. Add as many blocks as you want into each tab's region.
6. Save the layout.

## How it works

- In **Layout Builder edit mode**, each tab is shown as a clearly labelled
dashed box so the editor can see exactly which column they are dropping into.
- On the **front end**, a tab navigation bar is rendered and switching is
handled by lightweight vanilla JavaScript (no extra framework required). The
template uses Bootstrap grid classes (`col-lg-*`) for column layout, so a
Bootstrap-aware theme is recommended.
- The active tab and keyboard navigation (← →) are fully accessible via ARIA
attributes (`role="tab"`, `aria-selected`, `aria-controls`).
