SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @syncfusion/ej2-react-dropdowns, @syncfusion/ej2-react-inputs, @syncfusion/ej2-base, @syncfusion/ej2-data, and includes references (resource) components.

What problem does it solve? Building selection interfaces in React requires handling data binding, filtering, grouping, virtualization, and accessibility for each dropdown variant, which is time-consuming to implement correctly from scratch. ## Core Features & Use Cases - Seven Dropdown Components: Guidance for AutoComplete, ComboBox, DropDownList, ListBox, Mention, MultiSelect, and MultiColumn ComboBox from the @syncfusion/ej2-react-dropdowns package. - Data Binding & Filtering: Local arrays, complex objects with field mapping, remote data via DataManager adaptors, custom filtering events, and debounced search. - Advanced Scenarios: Virtual scrolling for large datasets, cascading dropdowns, custom item/group/header templates, disabled items, RTL, localization, and WCAG-compliant keyboard navigation. - Use Case: Build a country-state-city cascading form where the DropDownList filters as the user types, loads remote data through a server proxy, and renders grouped items with custom templates. ## Quick Start Ask the assistant to implement a Syncfusion React DropDownList bound to a JSON object array with filtering and a placeholder in your React application.

FAQPage Schema

How do I add a Syncfusion DropDownList to a React app?▼

Install @syncfusion/ej2-react-dropdowns, import the tailwind3 CSS files from ej2-base, ej2-inputs, and ej2-react-dropdowns, then render DropDownListComponent with a dataSource array and placeholder. Both functional and class components are supported.

How to filter a Syncfusion ComboBox with remote data?▼

Bind a DataManager with an ODataV4Adaptor or WebApiAdaptor as the dataSource, enable allowFiltering, and handle the filtering event with args.updateData and a Query. Route external API calls through a trusted server-side proxy rather than calling third-party URLs directly.

What is the difference between AutoComplete, ComboBox, and DropDownList in Syncfusion?▼

AutoComplete suggests matches as the user types into an input. ComboBox combines typed input with a selectable list and allows custom values. DropDownList restricts selection to predefined list items with optional search filtering.

Does Syncfusion React dropdown support virtual scrolling for large datasets?▼

Yes, set enableVirtualization to true and inject the VirtualScroll service with <Inject services={[VirtualScroll]} />. Only visible DOM elements render, and remote data fetches additional pages as the user scrolls.

How do I create cascading dropdowns in React with Syncfusion?▼

Handle the change event of the parent DropDownList and reload the child dropdown's dataSource based on the selected value. The references include patterns for multiple cascading dropdowns such as country, state, and city.

Why is my Syncfusion dropdown filtering not working with custom logic?▼

Custom filtering handlers must set args.preventDefaultAction = true to stop the built-in filter from running alongside your logic, then call args.updateData with your data and Query. Also verify the fields mapping matches your data columns.
