Hello John Paolo Caragdag.

Thank you for your purchase

Sounds like the drop-downs don't work - and since Multiselectbox requires a drop-down to open, that is why it's not working.

There is probably a conflict with the bootstrap.js files.

Please go to wpDataTables main Settings on your wp-admin page. You'll see Include full bootstrap front-end and Include full bootstrap back-end. Disable both sliders, hit Apply and refresh your page.

Please let me know if you managed to resolve the issue.

Best regards.

Hi again John Paolo Caragdag.

You're welcome, glad I could help.

That is default behavior of charts engine, but if you need some custom solution you can check in our documentation about wpDataCharts callbacks. 

• Every chart exposes several options that customize its look and feel. Charts usually support custom options appropriate to that visualization. wpDataChart callbacks allow adding options that are available in Google Charts API, Highcharts API and Chart.js API. 

• All necessary resources are available in charts engines API (depends on which one you use). Every engine has a different approach to chart settings. In wpDataChart callbacks you have to adopt those settings to the wpDataChart object (you can take a look at examples for each engine in our documentation, and also in Support help center). Huge number of examples for any area of programming can be found on stackoverflow.com (typing your problem in google and at the end add "site: stackoverflow.com" and google will search only that website). Also, a lot of examples of charts, chart settings and customization can be found on jsffidle.net (typing in google for example "line chart highcharts jsffidle")
• Please note that using hooks or wpdatatable and wpDataChart callbacks requires certain level of programming skills and included support refers only to advice.

Best regards.
