Tell us what you are trying to do?
I want to make an frontend form like the scrrengrab attached
The form should contain an edit link thet enables to change the checkbox value.
Is there any documentation that you are following?
No. But point me i the right direction.
Is there a similar example that we can see? hidden link
use the "updatera" button to change the attendees info.
Please do not misuse this site and do not edit anything more than trying out the checkbox values.
The form is updated so that everyone can see the new value.
The current application is outdated php version an needs to be updated to php7
What is the link to your site? hidden link
Can it be done with Toolset?
A Toolset front-end form is linked to a single post, so if each row in the table from your screenshot is a post, then you need not one form but a form for each row.
You can create a View to list the posts, and in the Loop Output section insert an edit form that edits the current post.
Each form will need its own submit button (but you can submit via ajax, and use the setting to keep displaying the form).
You will need to work on the markup/styling of the form to display the fields as a horizontal row.
