Beginning with WordPress v6.3, a Details Block is included in WordPress. This plugin is no longer needed.
The block allows you to easily show and hide content using built-in browser functionality. It doesn’t load any external JavaScript and relies on native HTML functionality. You can configure the appearance using built-in editor controls.
It uses the HTML <code>details</code> element to show and hide the content.

Details: Show and Hide

Steve

Adds the ability to enter contact information and output the details in your posts, pages or templates.
Based on the original “Contact Details” by 36Flavours, but the visible text has been translated to Dutch and a bankaccount field has been added.
Use the shortcode <code>[contact type="phone"]</code> to display any of the contact details, or use the function call <code><?php if (function_exists('contact_detail')) { contact_detail('phone'); } ?></code>.
Once you have defined a contact email address, use the shortcode <code>[contact type="form"]</code> to output the contact form.

Contact Details Enhanced

Adds the ability to easily enter and display contact information.
