Within my index I want to create a form like this one which can be edited, deleted and added from the same page with buttons,

I have bought the extensions package which includes mysql crud but I drag it and drop it from there what do I do, any tutorial to create for example something like this

Did you read the PDF documentation that came with the extension?
Can you tell what is unclear for you?

Yes, I have seen it, but it only shares the description of the script and its functions for each section.
I mean to have an example or tutorial applying it, so I could see how the configuration and even the creation are done. With a tutorial, even if it is with a basic table, so I can see and guide myself. Thanks

There is no specific tutorial.

Step 1.
Create the MYSQL table

Step 2
Configure the fields as described in the PDF.
