I have two users: admin and guest.
The admin user can add and edit the data in the database.
The guest instead has read only access.

In my application I want to hide the add button and the delete button when the guest logs.

How can I do it with Security Provider?

Thanks

Hello,
Please check this video tutorial:

Hello.
I do not need the data filtering.
Both users (ADMIN and GUEST) see the same data.

The first one, however, MUST SEE the two buttons ADD and EDIT.
The second one MUST NOT SEE the two buttons.

The video was useful for other solutions, not for this.
Do you have a different suggestion?
Thanks.

Just wrap the two buttons into a container and using the Data Bindings formatter change its class depending on the user identity.
So if
@useridentity = 1 / class = hidden
@useridentity = 2 / class = visible

You can just style the classes to set display:none/block

Thank you, Teodor, for your reply.
I got the answer that solved the problem.
I used the Data Bindings Formatter to change class depending on the user identity. Below the code.
Your extensions are powerful. Bravo!

     <span class="{{$SECURITY.identity.contains( "GUEST" ).then( "HIDDENCLASS", "VISIBLECLASS" )}}"> 
     <a href="#" class="btn btn-info" style="margin-right:20px;"> ADD </ a> 
         </ span> 
     </ li>

Thanks.
