fillModeString(default: undefined)
Controls how the color is applied to the button. When undefined (the default), the theme controls the default fill mode. Valid values are: "solid", "outline", "flat", "link".
The
"none"value is deprecated. Use custom CSS instead.
Example
<button id="dropdownbutton" type="button">Cancel</button>
<script>
$("#dropdownbutton").kendoDropDownButton({
items:[
{ text: "item 1" },
{ text: "item 2" }
],
fillMode: "outline"
});
</script>
