Hello Refael

Thank you for your purchase.

1. You can add new rows to all editable tables (manual, imported and SQL query based tables). 

2. The column needs to be either integer or float; you need to have at least 2 rows in there, and then in column settings, go to Filtering tab and choose the number range filter. You can also enable the number-range slider if you want.

If the drop-down doesn't work, you have a conflict with Bootstrap.js files of another plugin or the theme you're using.

Please go to wpDataTables settings, and disable "Include full bootstrap front-end". Check if it works after that. If it doesn't, please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. 

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. 

You can write credentials here just check Private Reply so nobody can see them except us.

Hello again Refael

Can you please tell me where I can see that issue? I was able to log into back-end, but I see drop-downs work there.

So, please tell me what table ID this affects, and where on front-end can I see the issue.

You're welcome, Refael

If you have any further questions or issues, please feel free to open a new ticket, and we'll gladly help.
