Question related Tables from Database?

Hi,

Thanks for contacting us here about this extension.

Can we use all Droptables: Table Themes and Charts in Tables from Database?

You have the ability to create charts from a database table. However, creating themes from a database table is not supported.

Can I enable custom filter in table from database in front-end? other than just filter in each column table head?

Regarding a custom filter, it's not available in the current version. However, we'll consider implementing it in future releases.
For now, you can use the filter at the header of each column.

is Droptable compatible with Bootstrap 5 Joomla template?

We haven't directly tested with it, but given that we utilize bootstrap, it should likely be compatible.

Cheers,
