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".\n\n> The \"none\" value is deprecated. Use custom CSS instead.
Example
<div id="fab-solid"></div>
<div id="fab-none"></div>
<script>
$("#fab-solid").kendoFloatingActionButton({
icon: "plus",
fillMode: "solid"
});
$("#fab-none").kendoFloatingActionButton({
icon: "plus",
fillMode: "none"
});
</script>
