Hi @alandres2628
Go to your list and click on CODE button which is mentioned in a screenshot.

Please add below code within <style></style> tag.
Here, in my example, there are two filter:
- Subject as a textbox filter
- Status as Dropdown filter
Now, you have to find out ids(using inspect element) of all the filter components(textbox, dropdown) and add that ids in clearFilter() function. you can see the first two lines which are for textbox id and dropdown id.
$(document).ready(function(){
var clearButtonHTML = "<button class='btn btn-default btn-entitylist-filter-clear' onclick='clearFilter()'>Clear</button>";
$(".btn-entitylist-filter-submit").after(clearButtonHTML);
});
function clearFilter()
{
$("#0").val("");
$("#dropdown_1").val("");
$(".btn-entitylist-filter-submit").trigger("click");
}
Result:
