Appearance
As of Kendo UI R1 2022, the FloatingActionButton component uses brand new rendering.
In this article, you will find information about the new rendering of the Kendo UI FloatingActionButton.
For additional information regarding the decision behind these changes, visit the Styling Overview article.
For a live example, visit the Appearance Demo of the FloatingActionButton.
Options
The Kendo UI FloatingActionButton supports the following styling options:
-
size
—configures the overall size of the component. -
fillMode
—configures how the color is applied to the component. -
themeColor
—configures what color will be applied to the component. -
rounded
—configures the border radius of the component.
Size
The size
option controls how big or small the rendered FloatingActionButton looks. The structure of the class is k-fab-{size}
.
The following values are available for the size
option:
-
sm
—small size -
md
—medium size -
lg
—large size -
none
—unset
The following example demonstrates how to configure the size
of the component through the component configuration:
<button id="fab"></button>
<script>
$("#fab").kendoFloatingActionButton({
size: "large"
});
</script>
The default size value is medium
and it is applied to the wrapping span element through the k-fab-md
class.
<button class="k-fab k-fab-sm">
</button>
FillMode
The fillMode
option controls the way the color is applied to the rendered FloatingActionButton. The structure of the class is k-fab-{fillMode}
.
You can set the fillMode
either to solid
or to null.
The following example demonstrates how to configure the fillMode
of the component through the component configuration:
<input id="fab" />
<script>
$("#fab").kendoFloatingActionButton({
fillMode: null
});
</script>
The default fillMode value is solid
and it is applied to the button element through the k-fab-solid
class.
<button class="k-fab k-fab-solid" >
</button>
ThemeColor
The themeColor
option controls the color that will be applied to the rendered FloatingActionButton. As applying themeColor
is closely related to the fillMode
, the structure of the class name for the themeColor
is composite - k-fab-{fillMode}-{themeColor}
.
The following values are available for the themeColor
option:
primary
secondary
tertiary
info
success
warning
error
dark
light
inverse
none
The default themeColor
value is primary
. A FloatingActionButton with default fillMode
and themeColor
will have k-fab-solid-primary
class applied.
<!-- FloatingActionButton with default fillMode and themeColor -->
<button class="k-fab k-fab-solid-primary k-fab-solid" >
</button>
<!-- FloatingActionButton with 'primary' themeColor and fillMode set to null -->
<button class="k-fab" >
</button>
<!-- FloatingActionButton with `solid` fillMode and `success` themeColor -->
<button class="k-fab k-fab-solid-success k-fab-solid" >
</button>
Rounded
The rounded
option controls how much border radius is applied to the rendered FloatingActionButton. The structure of the class is k-rounded-{size}
.
The following values are available for the rounded
option:
-
sm
—small border radius -
md
—medium border radius -
lg
—large border radius -
full
—largest border radius -
none
—unset
The example below demonstrates how to configure the rounded
of the component through the component configuration:
<input id="fab" />
<script>
$("#fab").kendoFloatingActionButton({
rounded: "large"
});
</script>
The default rounded value is full
and it is applied to the button element through the k-rounded-full
class.
<button class="k-fab k-rounded-full" >
</button>
Old vs New Rendering
- Previously the
themeColor
of the FloatingActionButton was applied using thek-fab-{themeColor}
class.
<!-- OLD -->
<button id="fab" class="k-fab k-fab-primary k-fab-lg k-fab-pill">
<span class="k-fab-icon k-icon k-i-home"></span>
<span class="k-fab-text">Home</span>
</button>
- Currently, the
themeColor
is applied using thek-fab-{fillMode}-{themeColor}
class. Additionally, classes forfillMode
androunded
are applied to the button element.
<!-- NEW -->
<button id="fab" class="k-fab k-fab-solid-primary k-fab-solid k-fab-md k-rounded-full">
<span class="k-fab-icon k-icon k-i-home"></span>
<span class="k-fab-text">Home</span>
</button>
Visual Backwards Compatibility
To achieve the same look and feel as the old rendering, you must update the element references.
When you use a LESS theme, the new styling and rendering supports only the default options.
The following example showcases how to customize the styles of the FloatingActionButton depending on the selected themeColor in both the new, and the old rendering:
<!-- Open the example in Dojo and select version prior to 2022 R1 to see the difference in the appearance -->
<button id="fab-primary"></button>
<button id="fab-secondary"></button>
<button id="fab-tertiary"></button>
<script>
$('#fab-primary').kendoFloatingActionButton({
themeColor: 'primary',
icon: 'home',
align: 'top start'
});
$('#fab-secondary').kendoFloatingActionButton({
themeColor: 'secondary',
icon: 'home',
align: 'top center'
});
$('#fab-tertiary').kendoFloatingActionButton({
themeColor: 'tertiary',
icon: 'home',
align: 'top end'
});
</script>
<style>
/* NEW RENDERING */
/* The style below will works with versions R1 2022 and later */
#fab-primary.k-fab-solid-primary{ /* applies border to primary FAB in the new rendering */
border: 2px solid yellow !important;
}
#fab-secondary.k-fab-solid-secondary{ /* applies border to secondary FAB in the new rendering */
border: 2px solid fuchsia !important;
}
#fab-tertiary.k-fab-solid-tertiary{ /* applies border to tertiary FAB in the new rendering */
border: 2px solid lime !important;
}
/* OLD RENDERING */
/* The style below will works with versions prior to R1 2022 */
#fab-primary.k-fab-primary{ /* applies border to primary FAB in the old rendering */
border: 2px solid red !important;
}
#fab-secondary.k-fab-secondary{ /* applies border to secondary FAB in the old rendering */
border: 2px solid blue !important;
}
#fab-tertiary.k-fab-tertiary{ /* applies border to tertiary FAB in the old rendering */
border: 2px solid green !important;
}
</style>
Best Practices
The Material Design guidelines dictate that:
When you configure the FloatingActionButton to display additional related actions (speed dial actions), you should configure only an icon for the button, without a label. Use labels to display additional information for the related actions.
If the application requires an icon and a label for the Kendo UI FloatingActionButton, consider omitting the additional actions.
<div id="fab"></div>
<script>
$(document).ready(function () {
$("#fab").kendoFloatingActionButton({
icon:"plus",
text: "Add To Cart"
});
});
</script>
Icons
The icon
configuration option specifies the name of an icon. The selected icon must be available in the Kendo UI theme that is rendered by the FloatingActionButton. For more details on the available Web Font icons see the Web Font Icons article
.
<div id="fab"></div>
<script>
$(document).ready(function () {
$("#fab").kendoFloatingActionButton({
icon:"plus",
items:[
{icon:"star",label:"Add Rating"},
{icon: "pencil", label:"Add Comment"}
]
});
});
</script>
