Load data in File System based on seleted combobox value

I have file system and combobox.
If user selected combo box, I need to call REST API with selected value and populate the data in filemanager.

Could you please provide me the working samples or piece of code to get more idea.

Hello,

You can send an Ajax GET request and pass the combo value into it as an URL parameter:

//"files" - ID of the File Manager
{view:"combo", on:{
   onChange:function(newv){
        $$("files").clearAll(); // if needed, clear the current data
        webix.ajax("../common/data.php?comboId="+newv, function(res){
            $$("files").parse(res);
        });
   }
}}
