Setup

Creating glossaries and terms

The Contao Glossary Bundle uses archives (glossaries) and glossary items (terms) similar to the Contao-News-Bundle.

1. Set up a redirect page for glossary items

2. Create a new glossary archive in Glossaries

3. Edit ✎ the new glossary to add new glossary items (terms)

4. Create a new glossary item:

   • Title = Glossary term
   • (Search terms = keywords for automatic conversion)
   • Glossary item teaser = teaser text for glossary overview etc.
   • Publish item

5. (Additionally, you are able to create content elements for detail pages - Similar to contao news)

Publishing your glossaries to your website

To display your glossaries and glossary terms, you have to create two front end modules:

Glossary overview

1. Create the front end module Glossary
2. Select your glossary/glossaries and configure the module

3. Embed the module in a page

Glossary reader

1. Create the front-end module Glossary-reader
2. Select your glossary/glossaries

3. Embed the module in your redirect-page (for your archive)

Automatic keyword conversion and hovercards

1. Go to your website root and "activate glossary" under glossary settings
2. Select your glossary/glossaries

3. (Enable hovercards if needed)

Only search terms within glossary items are taken into account. Not the keyword itself

You are able to add multiple keywords to a term. The glossary JavaScript does an exact search; thus spaces are allowed as well.

Hint:

You can disable automatic keyword conversion and hovercards within "Expert settings" on regular pages. This option is recommended for glossary pages.

Front end modules

Glossary

The glossary displays published glossary items from selected glossaries.

Settings

Glossaryreader

Page & Glossary settings

Root page settings

The contao glossary bundle extends the

Root page

with additional Glossary Settings.

The settings will work for all subpages for this root page.

All keywords within glossary items are converted to links by default (You are able to change the markup within the glossary configuration template, see JavaScript Settings)

The hovercard shows a preview of the glossary item

Regular page settings

The Expert settings for regular pages are extended with the following option:

Glossary archive settings

The Glossaries under Glossaries contain extra options for hovercards

The teaser images within glossary items are shown in the hovercard

Glossary item settings

Glossary items are terms within your glossaries.

Creating links in Contao

Automatic conversion creates links (or another markup) when entering the page through JavaScript. For SEO purposes, you are able to create real links within Contao using the following options:

Using Insert tags

For more information on Insert tags, please visit the

official Contao documentation.

Insert tags

You can use insert tags with the glossary id or its alias (aliases are generated and unique).

Example

TinyMCE / Link picker

When creating links in TinyMCE in the backend of Contao CMS, you are able to choose a new source "Glossary" in the link picker.

Known limitations

It is currently not possible to add hovercard-events to a link created via link picker through tinyMCE due to security reasons.

To apply a hovercard event to a link, edit the html within your tinymce, and add

data-glossary-id: "your glossary item id"

to your link.

Example

<a href="{{glossaryitem_url::430}}" target="_blank" rel="noopener" data-glossary-id="430">Domain name</a>

Glossary JavaScript

Markup of glossary keywords and behavior for hovercards can be changed by parsing options into the glossary initialization. The Glossary object can be found within the config_glossary_default template. Developers can create a new template with the following prefix: 'configglossary', and choose it in the root page settings.

Settings

// For example:
markupAttr: {
    'class': 'class1 class2',
    'data-myattr: 'attr'
}

'body',
'div,span,p',
'main,section,article',
'ol,ul,li',
'table,tr,th,tbody,thead,td',
'i,b,em,strong',
'mark,abbr',
'sub,sup'

'gl-none'

// For example:
'config':[
{
    "id": "1", // ID
    "keywords": ["Bar"], // Keywords
    "url": "glossar-detail\/bar.html", // Route
    "cs": 0 // Case-sensitive
},
{
    "id": "3", // ID
    "keywords": ["Foo"], // Keywords
    "url": "glossar-detail\/foo.html", // Route
    "cs": 0 // Case-sensitive
},
{...}
]

Enabling 'showLoadingAnimation' shows an empty hovercard until content is loaded

Frequently asked questions

The glossary term markup does not work on my website

• Make sure to check whether the glossary is activated in root page settings
• Make sure to check whether the glossary is not disabled for this subpage
• Check whether there is any JavaScript errors from other sources when opening developer tools
• Make sure to check for an existing <div id="wrapper"> container inside your <body>

  If you are using a custom theme, you have to adjust the glossary JavaScript within the template config_glossary_default.html. Here you can add an entry selector for the main content of your page as shown below ( See JavaScript Options):

  const GN = new Glossary({
    'entrySelector': "#YOUR-CONTENT-SELECTOR",
  

Not all links are converted on my page

• This only happens for Safari 16.3 and lower and there is no way around this, the simple solution is to buy a new device
• The JavaScript for the markup contains a fallback due to MacOS and Safari not allowing js-regex-lookbehind.
• Keywords with spaces (e.g. "Foo Bar") can not be found, full keywords ("Foobar") will still be taken into account.

I want to style the glossary markup

• In case you need a class, you have to adjust the JavaScript configuration within config_glossary_default.html
• Make sure to check the JavaScript-Settings for more options.

  const GN = new Glossary({
    'markupAttr': {
      'class': 'yourclass1 yourclass2'
    },
