How to delete Matrix fields in front end I created a user profile page with Matrix field with assets, I found this thread and this thread about adding and updating Matrix field in the frontend. Does anyone know how to delete the Matrix field? Moreover, I found that if I update Matrix field through the front end, it doesn't update the S3 bucket. Files are still stored in S3. Does anyone has a solution or give me a hint on delete/modify Matrix asset field? Thanks
I've managed to do this with:

&lt;form method="post" accept-charset="UTF-8"&gt;
    {{ csrfInput() }}
    &lt;input type="hidden" name="action" value="users/save-user"&gt;
    &lt;input type="hidden" name="userId" value="{{ currentUser.id }}"&gt;
    {% include '_partial/wish-list-fields' %}

    &lt;input type="hidden" name="fields[userWishListMatrix][{{ block.id }}][type]" value="null"&gt;

    &lt;input type="submit" value="Remove"&gt;
&lt;/form&gt;


The wish-list-fields partial include hidden inputs showing all the fields already there. e.g.:

&lt;input type="hidden" name="fields[userWishListMatrix][{{ block.id }}][fields][itemProperties][0][col1]" value="{{ row.property }}"&gt;


It repeats itself which I know doesn't seem terribly efficient but i dunno :-/ It works!

Please note, I'm on craft3 so things may be a little different (although most likely just the save-user / saveUser action).
