is it possible to use first row as a tags on it

Yes basudevkunwar,

Read my blog https://codexcoach.com/create-repeater-meta-box-in-wordpress/. That's have alI information. I think you need heading above of each field. You can put another table above of #repeatable-fieldset-one.

i already used your code sir,
i want to make first Cell as a taxonomy tag
like this

@webbycrown thanks for the code

I have question

How if I use this repeater for my option page?

What should I do?

Thanks so much
