Multiple filtering with dhtmlxCombo

hello there, I’m using the sample “05_oncheck” from dhtmlxCombo and I would like to filter the grid by one or multiple values depending on which checkbox is checked

so for instance if the User checks “john and smith” both should be displayed, the filter should not apply after filtering the first value.

Can the dhtmlxCombo be placed in the header of the grid?

All I need is guidance, that means please do not just send me to another link and tell me to read I did all of that already and I’m still a bit lost.

Thanks in advance!

Can the dhtmlxCombo be placed in the header of the grid?
You may place any needed html-content in your header:
mygrid.attachHeader("

")
then you need to attach your dhtmlxCombo to that container:
mygrid.loadXML(“data.xml”,function(){
var combo = new dhtmlXCombo(“combo_zone”);
