Are you tired of the default highlighting behavior in Cascader? Do you want to customize the filter highlighting feature to suit your application’s needs? Look no further! In this comprehensive guide, we’ll show you how to turn off filter highlighting in Cascader and explore alternative solutions to achieve the desired functionality.
Understanding Cascader Filter Highlighting
Cascader, a popular React component, provides a filtering mechanism to help users quickly find options within a large dataset. By default, Cascader highlights the matched text in the filtered options, making it easier for users to identify relevant results.
<Cascader
options={options}
onChange={(value, selectedOptions) => console.log(selectedOptions)}
filter={(search, item) => item.label.includes(search)}
/>
In the code snippet above, the `filter` prop is used to define the filtering logic. When the user types in the search input, Cascader highlights the matched text in the filtered options.
The Default Highlighting Behavior
By default, Cascader highlights the matched text using HTML `` elements, which wrap the relevant part of the label. This behavior can be observed in the following example:
Filtered Options |
---|
<strong> Option 1 </strong> |
Option 2 |
<strong>Option 3</strong> |
While the default highlighting behavior is useful, you may want to customize or disable it altogether to fit your application’s requirements.
Turning Off Filter Highlighting in Cascader
To turn off filter highlighting in Cascader, you can use the `renderFormItem` prop to customize the rendering of the filtered options.
<Cascader
options={options}
onChange={(value, selectedOptions) => console.log(selectedOptions)}
filter={(search, item) => item.label.includes(search)}
renderFormItem={(option, index) => <div>{option.label}</div>}
/>
In the code snippet above, the `renderFormItem` prop is used to render a plain `
Alternative Solutions for Custom Highlighting
While turning off filter highlighting is a simple solution, you may want to implement custom highlighting logic that better suits your application’s requirements.
One approach is to use a custom highlighting function that wraps the matched text in a specified element, such as a ``. You can then use CSS to style the highlighted text.
<Cascader
options={options}
onChange={(value, selectedOptions) => console.log(selectedOptions)}
filter={(search, item) => item.label.includes(search)}
renderFormItem={(option, index) => {
const label = option.label;
const match = label.match(new RegExp(search, 'gi'));
return <div>
{match ? <span>{match[0]}</span> : label}
</div>;
}}
/>
In the code snippet above, the `renderFormItem` prop uses a custom highlighting function to wrap the matched text in a `` element. You can then use CSS to style the highlighted text.
Another approach is to use a third-party library, such as react-highlight-words, to provide a more advanced highlighting functionality.
<Cascader
options={options}
onChange={(value, selectedOptions) => console.log(selectedOptions)}
filter={(search, item) => item.label.includes(search)}
renderFormItem={(option, index) =>
<Highlight>
<Highlighter
highlightClassName="highlight"
searchWords={[search]}
caseSensitive={false}
>
{option.label}
</Highlighter>
</Highlight>
}
/>
In the code snippet above, the `react-highlight-words` library is used to highlight the matched text with a custom class name.
Best Practices for Custom Highlighting
When implementing custom highlighting logic, keep the following best practices in mind:
-
Keep it simple: Avoid complex highlighting logic that can affect performance.
-
Use semantic HTML: Use HTML elements that provide meaning to the structure of your content, such as `` or ``, to wrap the highlighted text.
-
Style with CSS: Use CSS to style the highlighted text, rather than relying on inline styles or JavaScript.
-
Test thoroughly: Test your custom highlighting logic with different search queries and edge cases to ensure it works as expected.
Conclusion
Turning off filter highlighting in Cascader is a straightforward process, but it’s just the beginning. By implementing custom highlighting logic, you can provide a more tailored experience for your users and enhance the overall usability of your application.
Remember to keep your custom highlighting logic simple, semantic, and well-tested to ensure a seamless user experience.
