<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-ui-multiselect-widget/1.17/jquery.multiselect.js"></script>

Step2:

To have multi-select filter in search bar, add following properties with desired column:

// multi-select in search filter
$col["stype"] = "select-multiple";
$col["searchoptions"]["value"] = $str; // e.g. $str = "key1:value1;key2:value2;key3:value3"

It will replace search text box to multi-select filter for grid column name

$col = array();
$col["title"] = "Name";
$col["name"] = "name";


// this will prepare (key:value) option list for dropdown filters
$str = $g->get_dropdown_values("select distinct name as k, name as v from clients");


// multi-select in search filter
$col["stype"] = "select-multiple";
$col["searchoptions"]["value"] = $str;


$cols[] = $col;

If your column contains foreign key data (like client_id) then implementation will look like this:

$col = array();
$col["title"] = "Client";
$col["name"] = "client_id";
$col["dbname"] = "invheader.client_id";
$col["width"] = "100";


// this will prepare (key:value) option list for dropdown filters
$str = $g->get_dropdown_values("select distinct client_id as k, name as v from clients limit 10");


// in edit mode render as select
$col["edittype"] = "select";
$col["editoptions"] = array("value"=>":;".$str);


// multi-select in search filter
$col["stype"] = "select-multiple";
$col["searchoptions"]["value"] = $str;


$cols[] = $col;
