Problem:
Views filter (AJAX) doesn't work with Elementor

Solution:
The user has corrupted view settings and creating a new view works just fine with Elementor and AJAX filtering.

Problem:

How to add a value for the search dropdown default item instead of the blank label?

Solution:

Add the Javascript code below to the view:

function setDropdownDefaultValue() {
    jQuery('select[name="wpv-category"] > option:first-child').text('LABEL');
}
jQuery(document).ready(function() {
    setDropdownDefaultValue();
});
 
jQuery(document).ajaxComplete(function() {
    setDropdownDefaultValue();
});

replace LABEL with the label you want to add.
