Hello @Ajaychethi ,

 Means you have to set label bold on selection of particular value from selectbox ?

You can try onchange catalog client script :

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var element = g_form.getControl('bold_test')
    if (element) {
        var label = element.closest('.form-group').querySelector('label');
        if (newValue == 'Yes') {


            if (label) {
                label.style.fontWeight = 'bold';
            }
        } else {
            if (label) {
                label.style.fontWeight = '400';
            }
        }
        //Type appropriate comment here, and begin script below

    }
}
