Hi, assuming you are developing a plugin, you know what to do for insert tables with values, right?
So it easy solution: add a new value like checkbox, if marked by user for show the values of the plugin on item page, or not.
Let's suppose your function for this is: disable_attributes_job();
In your item.php:
if(disable_attributes_job() != true) {... the main function of your attributes jobs...}
Or something: if(disable_attributes_job() != 'enable') {... the main function of your attributes jobs...}
In item-post.php is something like: Selected box if you do not want showing the content of attributes jobs on ad [ ]
And with javascript you can use hidden div after box selected for hide all content fields of plugin on item-post.
That's it.
Regards
