Hello Manuel, Our tutorial uses Bootstrap 3 as the generators are based on Bootstrap 3. Actually Bootstrap 3 is what we recommend for building modern responsive websites, why do you deny using it? You can create an update record form the following way: 1. Create a server action with the query which returns all the results. 2. Create another server action with the same query, but this time filtered by a get variable. 3. On your page add server connect component and create the list of records, using the query returning all the records. 4. On your page, in app connect create a variable. 5. On click of the records which you created in step 4, dynamic events > variable > set value > select the id here. 6. Add another server connect component, from the filtered query, and in the get variable field set the variable value. 7. Create your update form and bind the vlaues from the filtered query to it. 8. Now in server connect create the update action and add it on the page, on submit.
