Drupal 8.x

I am looking for a module that will help me display a few lines on the front page of a site and when you click on a button, it will expand to full text or article. Probably using AJAX or jQuery.

Currently we can make a break point which will display a read more option but that will take us to a full node. I want to stay on the same page and same URL but expand a text area, that's all.

Anyone know of such a module or code?

In the case of having multiple databases aggregated into a .sql file dump of around 1Gb from PHPMyAdmin, but require just one database from the multiple databases dumped in the .sql file, to hopefully restore a drupal site which has crashed following an attempt to install some modules.

HI,

I made a page ( let's say the name of the page is A ) to let user check in. The page only show an QR code.

When the anonymous user visit A, scan the QR CODE, the Controller behind the page will Redirect to page B. In page B, it will show an ID to the user. And since i want  know who got the id , so i need to know the name and other things of the user.

So i made a Form to gather these things.

I watched a tutorial for setting up Drupal 8 on a Mac (https://www.youtube.com/watch?v=pOBArJn-tSQ) and the tutorial used MAMP.  Is MAMP required for using Drupal on Mac?

Seems, that some troubles with post articles on Facebook. On Wordpress all is good. So, maybe it's Drupal's problem.
