@devservicenow k Add the below code to exiting widget.

HTML:

<sn-choice-list
field="c.mychoice"
sn-model="c.mychoice"
sn-options="c.mychoicelistoption"
sn-value-field="myChoiceValue"
sn-text-field="myChoiceDisplay"
sn-items="c.mychoiceoptions"
sn-on-change="c.changeClass(selectedValue)">
</sn-choice-list>

Client controller:

c.mychoiceoptions = [
{
myChoiceDisplay:"All",
myChoiceValue:"all"
},
{
myChoiceDisplay:"Case records",
myChoiceValue:"case_records"
},
{
myChoiceDisplay:"Case tasks",
myChoiceValue: "case_tasks"
}
];

c.mychoicelistoption = {
hideSearch: true
};

c.mychoice = "all";

c.changeClass = function(taskType){
c.data.action = "change_class";
c.data.taskType = taskType;
c.server.update();
}

Server script:

if(input && input.action=="change_class"){
if(input.taskType == "all"){
inc.addEncodedQuery("task.sys_class_name=sn_customerservice_task^ORtask.sys_class_name=sn_customerservice_case");
}else if(input.taskType == "case_records"){
inc.addEncodedQuery("task.sys_class_name=sn_customerservice_case");
}else if(input.taskType == "case_tasks"){
inc.addEncodedQuery("task.sys_class_name=sn_customerservice_task");
}
}

Please mark as correct answer if this solves your issue.
