Thanks it is working great

Thanks Tareq I will try it out

I would have thought it being a standard as it is common to have a custom taxonomy for a custom post type. and tags are normally freely choosable not like categories which are normally well defined so a dropdown or checkbox will work for those, but they won’t work for tags. So yes for me it is one big thing missing to make this plugin incomplete.

Your current solution only allows a dropdown/checkbox and even that is not working nicely on custom tags (not categories)

I think they have a search plugin as well otherwise try the following plugin

http://wordpress.org/extend/plugins/advance-wp-query-search-filter/

What I actually mean is how do you save it as a proper taxonomy afterward in wordpress. so it is availabe as a non hierarchical taxonomy

and how do you save it into tag form afterwards ?

Your tag functionality for custom tags does not work. I get it working with a drop down, but it means you can not create new tags. and even with the drop down it does not work it some how allocates an id as the custom tag and creates a tag like that

ninja forms is having a solution where it seems to be working

I found out only that this is not an option after i just bought the plugin. I think it should be a standard inclusion in this plugin. It is just a pity I couldn’t read all the forum post as I need this in my requirements. I think the plugin is far from complete

Sorry forget the question I seen them now. my screen options for the custom fields were somehow turned of due to testing
