Class: Markawesome::TabsTransformer

Inherits:
BaseTransformer show all
Defined in:
lib/markawesome/transformers/tabs_transformer.rb

Overview

Transforms tabs syntax into wa-tab-group elements Primary syntax: ++++++[attributes]n+++tab1ncontentn+++n+++tab2ncontentn+++n++++++

Alternative syntax: :::wa-tab-group [attributes]n+++tab1ncontentn+++n+++tab2ncontentn+++n:

Attributes:

- placement: top (default), bottom, start, end
- activation: auto (default), manual
- active: panel name to show initially (e.g., "general", "tab-2")
- no-scroll-controls: disables scroll arrows

Constant Summary collapse

COMPONENT_ATTRIBUTES = 
{
  placement: %w[top bottom start end],
  activation: %w[auto manual]
