Hi there, I am working on development of a React Native App using EXPO cli, I cannot for the life of me get them to speak to each other, I have tried JWT and Simple Oauth and even pulling data by allowing all traffic through CORS, does anybody know of a tutorial or a resource to help set up react native with a headless Drupal 8 backend?

I have seen this featured showcase of the Icelandic food delivery company doing just this using Oauth but cannot find any guides or instructions on how to implement it.

I have created a custom block though Drupal Admin mentioning page restrictions (to show only on listed pages) and have included this block programmatically in a node twig file but, this block shows up in all the node pages rather than only mentioned pages. How to restrict this block to display only on restricted pages through coding?

I have already restricted the pages in block (created through Admin interface) but the block is being displayed irrespective of it's page restriction on all node pages.

Hello I have to do a search for my website. For this search, the search results should be displayed like a nested listed or tree, with parent and children elements, and it should be collapsible. The search results should be only display the titles of the content that have the entered keywords. When trying to do it with views and search api, it is only displaying as a list.

I wanted to know if there is a module or any other way to acheive this result. Thanks in advance 

Feeling guilty for asking this simple question.  I have a membership directory website for which I want to make a membership registration form. Could anyone let me know how to make this form? The form is supposed to ask users to write their user id and password in the provided text boxes apart from the other necessary fields. May I know whether this form will be any different from a regular web form?  If yes, how should I start and what are the major differences between a regular form and a member registration form?

Thanks in advance and regards,
