The plugin provides in the block editor 2 types of spoilers:

  • Pequeño spoiler

Little Spoiler – small spoiler for plain text.

Box spoiler – consists of 2 blocks:
Opening spoiler (Box Spoiler Start) and closing spoiler (Box Spoiler End)
Between them, you insert any block (or several block’s) with content that you want to hide.

In the frontend, the spoiler (accordion) opens with animation.
In the editor you can choose the color design of the spoiler.

⭐⭐⭐⭐⭐ Спасибо автору за плагин, альтернатив для Gutenberg не нашёл. Плагин работает хорошо, форматировать уже имеющийся текст очень удобно. Автор ответил на мой вопрос на форуме и помог с кастомизаций плагина под сайт.

Easy to use spoiler plugin (to show or hide content-blocks as an accordion). Simple styled title row with heading, showing or hiding the complete following content-block or only a chunk of text. Looks well in desktop and mobile mode. (For better adaption of different website-designs it would be great if the color of the used borders for title-box and expanded content-box could be easily set via custom CSS code 😉

The most important feature for me was the box spoiler feature. After testing a little bit I can say that everything works fine! 🙂 Maybe you could implement custom colors into GUI.

The best spoiler plugin ever. Please keep up the good work and then eventually it will get more popular 🙂 Thank you!

This is hands down the best spoiler plugin for Gutenberg. It comes with 2 options to choose from: a simple spoiler for text only, and 2-piece spoiler which can be used with any blocks. The way it works is very simple, yet very effective. You just add some Gutenberg blocks between a START SPOILER and END SPOILER blocks, and you get a very good looking dropdown. Very happy with the plugin!
