How to control visual layout of DropDownListPopupSettings ... list of the .k class selectors?

[Rob]

I've tried to find documentation on how to modify the CSS for the dropdownlist and it's popup but can't seem to figure out how to change the "Search" area size, nor the "Select Type" (they are too large).

I was able to figure out how to adjust the actual items:

.custom-compact-dropdownlist-popup .k-list-item {
    padding-top: 2px;
    padding-bottom: 2px;
    font-size: 0.90em;
}

and reference:

<DropDownListSettings>
    <DropDownListPopupSettings Class="custom-compact-dropdownlist-popup" />

but I don't know what to use in CSS ... is there a list somewhere of the ".k" class selectors?

Rob.
