The Blazor ComboBox component is a dropdown list with an editable option that also allows users to choose an option from a predefined pop-up list. It can be used as an alternative to the HTML select tag and has several out-of-the-box features such as data binding, filtering, grouping, cascading, templates, UI customization, pop-up list and customization.
This editable combo box in Blazor allows the entry of a custom value when the option the user searched for is not available in the pop-up list. You can also set a value for the combo box or get the selected value from the combo box at any time through the interactive APIs.
Built-in filtering support with a rich set of filtering configurations is available to meet all your application needs.
Filter queries are customizable, and you can use your own filter libraries to filter data.
The Blazor ComboBox component supports diacritic character sensitivity. This behavior can be turned on or off.
The filter search can be customized with case sensitivity and can be performed with minimum query string characters.
Group the pop-up list items with a corresponding category that makes it easy for users to pick an item quickly from the dropdown and also improves the visual experience for users.
The autofill option allows users to easily search through options in the combo box. When a user is typing a query string to search, the available matching options will be filled automatically.
The Blazor ComboBox component provides an option to create multiple cascading combo boxes, which helps users populate data for a child combo box based on the current selected value of the parent combo box.
Since the ComboBox is a form component, it supports HTML forms, template-driven forms (Angular), and reactive forms.
The Blazor ComboBox component supports a responsive mode that provides an adaptive, redesigned UI appearance for mobile devices and touch actions.
Fully supports WAI-ARIA accessibility guidelines to work with screen readers and assistive devices.
Follows WAI-ARIA best practices for implementing keyboard interaction.
Follows WCAG 2.0 standard in UI element visual design such as for foreground color, background color, line spacing, text, and images.
Supports right-to-left (RTL) rendering for users working in right-to-left languages like Hebrew, Arabic, or Persian.
Developers can customize all UI elements and control their behaviors according to the end user’s requirements using the control’s rich set of client-side APIs.
Easily get started with the Blazor ComboBox using a few simple lines of C# code example as demonstrated below. Also explore our Blazor ComboBox Example that shows you how to render and configure the Blazor ComboBox component.

Syncfusion Blazor ComboBox provides the following features:
We do not sell the Blazor ComboBox separately. It is only available for purchase as part of the Syncfusion Blazor suite, which contains over 70 native Blazor components, including the ComboBox. A single developer license for the Syncfusion Essential Studio for Blazor suite costs $995.00 USD, including one year of support and updates. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.
You can find our Blazor ComboBox demo here.
No, our 70+ Blazor components, including ComboBox, are not sold individually, only as a single package. However, we have competitively priced the product so it only costs a little bit more than what some other vendors charge for their ComboBox alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 70+ Blazor components for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.
No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.
A good place to start would be our comprehensive getting started documentation.
