Thanks for the video!
A tip: the remove buttons should also be button tags instead of spans because the keyboard can't select a span, which is not semantic.

Nicely done, thank you for sharing. It might be a lot to ask but it would be very interesting to see the template drive equivalent approach.

Thanks,
It would be really useful to have a form builder that automatically types the form according to its initialization

[joao_penas]

Nice example 👌
Just curiosity, why use FormBuilder, and not FormGroup and FormControl for build the form 😊?
By the way, one good point to improve would be add an id to identify the question, because if lately would like apply some filter, the removed question with index could be different and remove unwanted question.
Continue the good work 😊

i really wonder if we can add an API based validation in a dynamic form in angular 17 /18 such as captcha validation or populate cities from multiple countries in a auto complete field in nonnullable forms etc.

Hi, would you know if I have a component A which extends a directive B.
And in comp. a I am in injecting a service A with inject and inside of the constructor I am also calling super and injecting the service A. The question is, am I creating 2 instances os service A? Thanks in advance.

Problem. We get a bug if:
1) Create a second input
2) Set it to some value
3) Delete the first input

I'm that 20%, love you since I found you haha :P

I written your example in my side and it dos not works well, for example if you add 2 question and fill those fields and then remove first question in UI side remove seconds and typescript side remove first, then i refactored code, instead of @for i used *ngFor and typescript side form control value instead of empty string i written new formControl() after that it works well; please chek your example one more time and see yourself what is going on. thanks

Final result has empty string at first answer, probably solution has mistake somewhere
