Thanks Elliot for the response.
This is a frond end of a website.
So, if I’m to add this “save button”, what acf function should I call? Any example for this out there?
Sorry again for the confusion. I actually do not want the default value the example I showed is what I wanted.
This is a custom post that I created. I just add this in the field group using “custom field”, and see it in the front post page.
Thanks
