Horizontal Tabs

Module for Drupal 8 that adds 'horizontal_tabs' form element, similar to the 'vertical_tabs' element that is already included in core.

The 'vertical_tabs' form element in core is a great addition to Form API in Drupal 8, which let's you easily add vertical tabs to any form with a minimum amount of code to write. Unfortunately there isn't a corresponding horizontal tabs form element.

I've only found an issue in the issue queue on drupal.org, that isn't really frequented very much: https://www.drupal.org/node/1168364.

This module aims to fill this gap. It's basically a shameless 1:1 copy of core's vertical tab form element (renamed everything to horizontal of course) with an adjusted CSS that displays the tabs horizontally instead of vertically. This makes it exactly as easy to use as the vertical_tabs element, meaning that you could easily swap any usage of vertical tabs to horizontal ones just by changing the form elements type form 'vertical_tabs' to 'horizontal_tabs'.

DEPRECATION NOTICE

use field_group module instead for horizontal tabs, see #3362594: Deprecate in favor of Field Group module.
