Decidim allows you to share a information box related to some spaces as:
Meetings component in an easy way with the
embeddable option that offers the platform.
All that you have to do, is to enter into whathever space/component you want to share info to, and look for down right part of the page to find embeddable share option.
If it is embeddable, you will see
embed <\> option there.
Then you can click there, and following that, a new window will pop up showing you the necessary code to embed that space’s info into where you want through the html given code in form of a card view.
That is all!
