Is it possible to refine the filter options in a OptionsConnector contruct, e.g. using your example

    $filter1 = new OptionsConnector($res);




I have something similiar, but I want to filter the results of the lookup table first, e.g. in the example above say you wanted to show the countries from the table where country_name was like %a%, i.e. all countries beginning with ‘a’


it is possible you can try to use render_sql method instead of render_table: dhtmlx.com/dhxdocs/doku.php?id=d … iting_data

for example

$filter1->render_sql(“select * from countries where country_name like ‘%a%’ “,“country_id”,“country_name(value)”,””,"");

instead of
