This module includes the configuration for a content type, a few Paragraphs and their related fields and image styles which serve as a starting point for creating content. This configuration is located in the /config/optional folder and will be automatically imported when the module is installed.
Due to the nature of Drupal's configuration import system, once the module is installed on a site, you will need to follow the standard site-wide configuration export and import workflow to make edits.
Future modifications to the config files in config/optional will not override existing configuration during the normal config import process, but can be imported with the following drush command.
drush cim -y --partial --source=modules/contrib/fsu_strata_mercury_editor/config/optional
This module includes the configuration for the Enhanced Page content type. This content type includes a Paragraph field called field_content. The settings for this field control which Paragraphs are available to content editors when authoring an Enhanced Page.
This module includes configuration for a few basic Paragraphs types – a.k.a Components. See /admin/structure/paragraphs_type. At the time of this writing, this module contains two general Paragraph types, Text and Image, two FSU Strata specific types, Hero and Card and one Layout Paragraphs type called Section.
The Section Paragraph type, which has no fields itself, allows content editors to add a section, or row, to a page and choose a corresponding layout. Once a Section is added, newly created Paragraphs can be added to different regions within the layout of that Section. An Enhanced Page can contain multiple sections with varied layouts.
Custom layouts are registered in fsu_strata_mercury_editor.layout.yml. Each layout's Twig template, and any required CSS and JS should be saved in a corresponding folder within /layouts. See How to register layouts for more information about available options. In order to make use of the Style Options module in your layout, you must explicitly define its class property as \Drupal\style_options\Plugin\Layout\StyleOptionLayoutPlugin.
In order for newly created layout to appear as an option for content editors, you must enable it on the Section paragraph at /admin/structure/paragraphs_type/section
Mercury Editor uses the Style Options module to provide flexibility for content editors when authoring content.
Style Options are defined in fsu_strata_mercury_editor.style_options.yml. To add a new style option set, you first define the general set of options, or choices an editor can make. You then declare the context (currently Paragraph, Layout and/or Region) in which a given option should be available. For example, you might want the Custom Class option, which allows content editors to input custom CSS classes that will be added to an element, available by default on all Paragraphs, Layouts and Regions. However the Hero Style options, which is very specific to the Hero component, should only be available when editing Hero paragraphs.
How the chosen value from a Style Option gets applied to a Paragraph, Layout or Region is dictated by the corresponding StyleOption plugin. The Style Options module provides a couple useful plugins out of the box, such as CSS Class and Background Image. This module includes additional StyleOption plugins developed specifically for FSU.
The first is Property. This simply passes the corresponding value onto the theme system for use within preprocess functions or Twig templates. This is useful in cases where a single CSS Class isn't sufficient enough to achieve desired style. For example, the Card Style requires alternative markup for adding the Point or Arrow effects.
See /src/Plugin/StyleOption/Property.php
The second is ImageStyle. This allows content editors to choose which aspect ratio an image should appear in. This plugin will render the source image in the corresponding image style.
See /src/Plugin/StyleOption/ImageStyle.php
This module includes configuration for additional aspect ratio specific images styles as defined by the FSU Style Guidelines. For scaled image styles the naming convention is Max 1200x800 which means an image should be scaled down so it is no more than 1200px wide and 800px tall – without cropping.
For cropped images, these image styles follow a naming convention of [x]:[y] [width]x[height]. For example 1:1 180x180 is a square image that is 180px by 180px. While this module is not currently configured to use responsive images, we've found following this naming convention to be very when implementing them.
Additionally, all the cropped image styles make use of the Image Widget Crop module. This module allows content editors to upload any image then interactively specify how it should be cropped at different aspect ratios.
Since the intention of this module is to make it work with the existing Strata theme, very little custom CSS is required for layouts and components. However, we do need to heavily control the markup via Twig templates. In order to keep this functionality modular and avoid making edits to the Strata theme, we need the ability to override Paragraph templates in this module. To do so, we must define our own custom theme hooks for specific Paragraphs. See fsu_strata_mercury_editor_theme() in fsu_strata_mercury_editor.module for more information.
There are additional user permissions related to this module. Since permissions configuration is managed at the user role level, and the role config files contain information that is outside the scope of this module, we must grant permissions programmatically as this module is installed. See fsu_strata_mercury_editor_install() in fsu_strata_mercury_editor.module for more information. In order for any changes to these permissions to take effect, you must uninstall and reinstall this module.
