<ul>

</ul>
<h3>Use</h3>
Drag an Accordion block into a post or page or CPT and use the ‘Add pane’ button at the bottom of the block to add pane-blocks.
<h3>styling</h3>
At the root some basic styling variables are defined that can be overwritten by your theme. Some of these can be changed ad hoc by the user in de block-editor. These are:
<pre><code> --wp--custom--accordion--transition-time: 0.1s;
 --wp--custom--accordion--margin-top: 0px;
 --wp--custom--accordion--margin-right: 0px;
 --wp--custom--accordion--margin-bottom: 0.1em;
 --wp--custom--accordion--margin-left: 0px;
 --wp--custom--accordion--header-padding-top: 0.5em;
 --wp--custom--accordion--header-padding-right: 2em;
 --wp--custom--accordion--header-padding-bottom: 0.5em;
 --wp--custom--accordion--header-padding-left: 2em;
 --wp--custom--accordion--content-padding-top: 0.5em;
 --wp--custom--accordion--content-padding-right: 2em;
 --wp--custom--accordion--content-padding-bottom: 0.5em;
 --wp--custom--accordion--content-padding-left: 2em;
 --wp--custom--accordion--header--text-color: #ffffff;
 --wp--custom--accordion--header--background-color: #666666;
 --wp--custom--accordion--header--active-text-color: #ffffff;
 --wp--custom--accordion--header--active-background-color: #999999;
 --wp--custom--accordion--body--text-color: #ffffff;
 --wp--custom--accordion--body--background-color: #666666;
</code></pre>
The default values can also be defined in the theme.json of your (child-) theme:
Add them to the theme.json like so:
<pre><code>{
 "$schema": "https://schemas.wp.org/wp/6.7/theme.json",
 "version": 3,
 "settings": {
 "custom": {
 "accordion": {
 "transitionTime": "0.1s",
 "marginTop": "0px",
 "marginRight": "0px",
 "marginBottom": "0.1em",
 "marginLeft": "0px",
 "headerPaddingTop": "1em",
 "headerPaddingRight": "1em",
 "headerPaddingBottom": "1em",
 "headerPaddingLeft": "1em",
 "contentPaddingTop": "0.5em",
 "contentPaddingRight": "2em",
 "contentPaddingBottom": "0.5em",
 "contentPaddingLeft": "2em",
 "headerTextColor": "#ffffff",
 "headerBackgroundColor" : "#666666",
 "activeHeaderTextColor": "#ffffff"
 "activeHeaderBackgroundColor": "#999999",
 "bodyTextColor": "#000000",
 "bodyBackgroundColor" : "#ffffff",
 }
 }
 }
}<h3>Accessability</h3>The pane-headers have a tab-index. If the Enter-key is pressed while a pane-header has focus, a click-event is triggered on that pane-header thereby activating / opening it.
</code></pre>

Advanced Accordion Gutenberg Block – Create Beautiful FAQs, Content Accordions & Interactive Tabs

The colour picker does not support the colour palettes of the theme.json. Furthermore, the plugin unfortunately does not keep its core promises. According to the description, the plugin does not use any frameworks and pure vanilla Javascript. However, dashicons are loaded in the frontend for the icons - from a PageSpeed perspective, individual SVGs would be a much better choice here. Furthermore, the Javascript was written with jQuery dependency, so jQuery is mandatory and loaded in the frontend. So there is no question of Pure Vanilla Javascript here.

Not as exptected

When ever the plugin is updated the accordions used in pages show a message saying "Block contains unexpected or invalid content." and a button inciting us to recover the block.  When the button is clicked, the group accordion block disappears with all the content and one has to start all over from scratch.... not an optimal solution.

Unfortunately keeps breaking on updates

Create stunning FAQ & accordion blocks. SEO-optimized, fully accessible, zero performance impact. No coding needed.
