Chip Component
The Ignite UI for Blazor Chip is a compact element that represents a tag, filter, or person and that users can select or remove.
A chip can be selectable, removable, or both, and can show icons or other content before and after its label.

Anatomy
The Blazor Chip is a container that holds a label and optional icons in a single row.
igc-chip // host

│ ├─ slot[name="end"] // content before the suffix content
│ └─ slot[name="suffix"] // content after the label
└─ span[part="remove"] // rendered when removable and not disabled
└─ slot[name="remove"] // default remove icon button
Getting Started
Install Ignite UI for Blazor and configure a theme, as described in the Getting Started topic, before you add the Blazor Chip to an application.
Register the Ignite UI for Blazor services:
// in Program.cs file
builder.Services.AddIgniteUIBlazor();
Registering IgbChipModule, the client resource module of the IgbChip, is optional: the component loads its resources when it first renders. Listing it in builder.Services.AddIgniteUIBlazor(typeof(IgbChipModule)) can be used to preload resources or to support elements created only on the client (see Component Modules).
Add the theme stylesheet to your host page.
<link href="_content/IgniteUI.Blazor/themes/light/bootstrap.css" rel="stylesheet" />
Prerequisites and Version Compatibility
Some Blazor Chip features depend on the package version that your application uses.
Use the IgniteUI.Blazor package. IgniteUI.Blazor 26.1 ships an earlier version of the chip:
IgbChipdoesn’t expose theOutlined,Locale, orResourceStringsproperties.- The
basepart is the selection button, and the remove icon renders inside it. The chip has noactionorremoveparts. - The focus styles read
--ig-chip-focus-outline-colorand--ig-chip-focus-selected-outline-color. - The keyboard and screen reader behavior differs, as described in Accessibility.
Usage
Add a label to the Blazor Chip, then add icons, a type, a size, and selection or removal as your layout needs.
Layout
The Blazor Chip supports content templating around its label. Place content in the prefix and suffix slots to show it before and after the label, such as text or an Icon. Icons in the chip follow its size, so they also come in three sizes: large, medium, and small.
Place the label in the default slot. The start slot renders before the prefix content, and the end slot renders before the suffix content. Use the select and remove slots to replace the default select and remove icons.
<IgbChip Selectable="true" Removable="true">
<IgbIcon slot="select" IconName="check" Collection="material" />
<IgbIcon slot="prefix" IconName="person" Collection="material" />
Ana Zane
<IgbIcon slot="suffix" IconName="mail" Collection="material" />
<IgbIcon slot="remove" IconName="close" Collection="material" />
</IgbChip>
Custom content in the remove slot replaces the default remove icon, including its focus and accessible label. Make the replacement focusable and give it an accessible name.
Types
The Blazor Chip provides two types: Default and Primary.
Leave Variant unset for the default type, or set it to StyleVariant.Primary for the primary type. The variant also accepts StyleVariant.Info, StyleVariant.Success, StyleVariant.Warning, and StyleVariant.Danger for status colors.
<IgbChip>Default</IgbChip>
<IgbChip Variant="StyleVariant.Primary">Primary</IgbChip>
Size
The Blazor Chip comes in three sizes:
- Large: suitable for interactive scenarios, such as action triggers.
- Medium: suitable for short areas, such as the recipient field of an email composer.
- Small: suitable for data-dense scenarios, such as the values in a grid cell.
Set --ig-size to var(--ig-size-small), var(--ig-size-medium), or var(--ig-size-large) to change the chip size. Set it on a chip, or on a container to size all chips inside it.
.filter-chips {
--ig-size: var(--ig-size-small);
}
Interaction State
The Blazor Chip can be enabled or disabled.
Set Disabled to prevent interaction. A disabled chip can’t receive focus or be selected, and it doesn’t render the remove icon, even when removable is set.
<IgbChip Disabled="true">Archived</IgbChip>
State
When users interact with the Blazor Chip, it changes from its default idle state to hover, focused, and selected.
The selected state needs selection to be enabled. Set Selectable to let users toggle the chip by clicking it or pressing Space or Enter. Each toggle updates Selected and emits a selection event with the new state. Set selected to define the initial state.
The select icon and the pressed state appear only when selectable is set.
<IgbChip Selectable="true" Selected="@isBold" SelectedChanged="OnSelectedChanged">Bold</IgbChip>
@code {
private bool isBold = true;
private void OnSelectedChanged(bool selected) => isBold = selected;
}
Remove Chip
A removable Blazor Chip shows a remove icon at its end that users activate to request the chip’s removal.
Set Removable to show the icon. Activating the icon emits a remove event, but the chip stays on the page. Remove the chip, or the item it represents, in the event handler.
Assign a JavaScript handler through RemoveScript, and register it with igRegisterScript in a script file that your host page loads.
<IgbChip Removable="true" RemoveScript="handleChipRemove">Angular</IgbChip>
function handleChipRemove(event) {
event.target.remove();
}
igRegisterScript("handleChipRemove", handleChipRemove, false);
Chips Area
To organize a collection of chips, place them in a container that lays them out with a gap, such as a wrapping flex container.
The Blazor Chip has no separate chips area component, so the container’s CSS sets the layout.
.chips-area {
display: flex;
flex-wrap: wrap;
gap: 0.5rem;
}
Do/Don’t
When using a Chip, the obround will automatically size itself to fit the content and you only need to adjust the size of the instance accordingly. If the Chip is used as an action trigger for related content, avoid using it in scenarios where there is only one available action, or for configurations presenting only one selectable option.
DoUse chips for grouped actions or a small set of related options.
Don’tAvoid using a chip for single actions or single choices.Properties
The Blazor Chip exposes properties for selection, removal, state, and appearance.
| Name | Type | Default | Description |
|---|---|---|---|
Disabled |
bool |
false |
Disables the chip and hides the remove icon. |
Removable |
bool |
false |
Shows the remove icon. |
Selectable |
bool |
false |
Lets users toggle the selected state. |
Selected |
bool |
false |
Sets the selected state. |
Variant |
StyleVariant |
n/a | Sets the predefined color variant. |
Events
The Blazor Chip emits events when users select or remove it.
| Name | Description |
|---|---|
SelectedChanged |
Raised with the new selected state when the user toggles a selectable chip. |
Select |
Raised when the user toggles a selectable chip. Use SelectScript to handle it in JavaScript. |
Remove |
Raised when the user activates the remove icon. Use RemoveScript to handle it in JavaScript. |
Styling
Style the Blazor Chip with its CSS variables for token-level changes, and with its CSS parts when you need to target a specific element.
| Variable | What it changes |
|---|---|
--ig-chip-background |
Background of the default (not outlined) chip. |
--ig-chip-text-color |
Text color of the default chip. |
--ig-chip-outlined-background |
Background of the outlined chip. |
--ig-chip-outlined-text-color |
Text color of the outlined chip. |
--ig-chip-border-color |
Border color of the outlined chip. |
--ig-chip-border-radius |
Corner radius of the chip. |
--ig-chip-hover-background |
Background of the default chip on hover. |
--ig-chip-focus-background |
Background of the default chip on focus. |
--ig-chip-focus-shadow-color |
Focus shadow color in the Bootstrap and Indigo themes. |
--ig-chip-selected-background |
Background of a selected chip. |
--ig-chip-selected-text-color |
Text color of a selected chip. |
--ig-chip-disabled-background |
Background of a disabled chip. |
--ig-chip-disabled-text-color |
Text color of a disabled chip. |
--ig-chip-remove-icon-color |
Color of the remove icon. |
--ig-chip-remove-icon-color-focus |
Color of the remove icon on focus. |
--ig-chip-size |
Height of the chip. |
--ig-size |
Shared component size token used to derive the chip size. |
In IgniteUI.Blazor 26.1, the chip has no outlined style, so --ig-chip-outlined-background and --ig-chip-outlined-text-color have no effect. The chip reads --ig-chip-focus-outline-color and --ig-chip-focus-selected-outline-color instead of --ig-chip-focus-shadow-color.
| CSS Part | Description |
|---|---|
base |
The selection button that wraps the prefix, content, and suffix. |
prefix |
The container for the select icon and the start and prefix content. |
content |
The wrapper around the default slot. |
suffix |
The container for the end and suffix content, and for the remove icon. |
Sass Theming
Use the chip-theme function when your application customizes Ignite UI themes through Sass. Set $background, or $outlined-background for outlined chips, and the theme derives the text, hover, focus, and selected colors from it. Override any other parameter when you need a specific value.
@use "igniteui-theming/sass/themes" as *;
$custom-chip-theme: chip-theme(
$background: #011627,
$remove-icon-color: #fecc47
);
:root {
@include tokens($custom-chip-theme);
}
CSS Variables
Set the chip CSS variables directly when you need local styling without a Sass build step. Set them on a chip, or on a container to style all chips inside it.
.filter-chips {
--ig-chip-background: var(--ig-primary-500);
--ig-chip-text-color: var(--ig-primary-500-contrast);
--ig-chip-remove-icon-color: var(--ig-primary-500-contrast);
}
To style a single element of the chip, target its CSS part.
igc-chip::part(suffix) {
color: var(--ig-gray-400);
}
Styling with Tailwind
You can style the Blazor Chip with Tailwind utility classes, and set its CSS variables through arbitrary properties such as [--ig-chip-background:var(--ig-primary-600)]. Make sure to set up Tailwind first, as described in Tailwind.
Accessibility
The Blazor Chip supports keyboard operation and exposes its state to assistive technology.
Keyboard Interaction
Keyboard users reach each chip with Tab, followed by its remove control when the chip is removable. Disabled chips are skipped.
| Key | Action |
|---|---|
| Space / Enter | On a removable chip, toggles Selected when Selectable is set and raises the select event. On the remove icon, raises the remove event. |
In IgniteUI.Blazor 26.1, on a chip that isn’t removable, Space doesn’t toggle the selection, and Enter toggles it and also raises the remove event.
Screen Readers / ARIA
The Blazor Chip exposes its state through native semantics and ARIA attributes.
- The chip is a native
button. WhenSelectableis set,aria-pressedreflects theSelectedstate. - The default select icon has the
aria-label“select chip”. - The default remove icon, with
role="button",tabindex="0", and thearia-label“remove chip”, renders inside the chip’s button, so it’s a nested control. - Because the icons render inside the button, the accessible name of the chip includes their labels, for example “Chip remove chip”.
- A disabled chip disables its native button, so assistive technology reports the chip as unavailable.
Accessibility Compliance
Infragistics documents Ignite UI for Blazor accessibility support for Section 508 and WCAG 2.1 guideline areas in the Accessibility Compliance topic.
| Criterion | How the component complies |
|---|---|
| 1.4.1 Use of Color | A selectable chip shows the select icon while it is selected, in addition to its selected colors. |
| 2.1.1 Keyboard | On a removable chip, the chip and its remove icon both work with Space and Enter. On a chip that isn’t removable, only Enter toggles the selection, as described in Keyboard Interaction. |
| 2.1.2 No Keyboard Trap | Tab and Shift + Tab move focus out of the chip, which never holds focus. |
| 2.4.3 Focus Order | Focus moves from the chip to the remove icon in document order. |
| 2.4.7 Focus Visible | The focused chip shows a focus background, plus a focus outline in the Bootstrap and Indigo themes. |
| 4.1.2 Name, Role, Value | The chip is a native button that exposes its pressed state. The remove icon exposes a button role and a label, but it renders inside the chip’s button, so the two aren’t separate controls. |
Your responsibilities:
-
Give every chip a text label that identifies the item it represents.
-
Move focus to a logical place, such as the next chip, after you remove a chip in the remove event handler.
-
Keep sufficient contrast between the chip background and its text and icons when you override the theme colors.
-
Keep a visible focus indicator when you restyle the chip.
-
Keep chips and their remove controls large enough to tap when you use the small size or a custom
--ig-chip-size. -
Keep custom
removeslot content focusable and labeled, as described in Layout.
Known exceptions:
- In releases based on
igniteui-webcomponents7.4.1 and earlier, anaria-labelset on the chip element doesn’t reach the selection button, so it doesn’t change the chip’s accessible name. Name the chip through its content instead.
Troubleshooting
Use this section when a chip doesn’t behave or look as expected after a change or an upgrade.
Why does the chip stay on the page after I click the remove icon?
The remove event only notifies your application. Remove the chip in the event handler, as shown in Remove Chip.
API References
Dependencies
The Blazor Chip renders its default select and remove icons with the IgbIcon component, which is included with the chip.
Register any custom icons that you place in the chip slots.
The chip also uses the shared theme stylesheet for its default appearance.

FAQ
A Ignite UI for Blazor Chip represents an item, such as a tag, filter, or recipient, that users can select or remove. A Button runs a single command, so choose it when users trigger an action rather than pick or dismiss an item.
Handle the selection event of each Ignite UI for Blazor Chip in the group. When a chip becomes selected, set selected to false on the other chips.
Yes. Put your own content in the remove slot of the Ignite UI for Blazor Chip, and keep that content focusable and labeled, because it replaces the built-in control.
Not directly. The Ignite UI for Blazor Chip has no drag or reorder support, so change the order of the chips in your data or markup.
Assign one of the shared size tokens, var(--ig-size-small), var(--ig-size-medium), or var(--ig-size-large), to the --ig-size CSS variable of the Ignite UI for Blazor Chip.
