React suite is a library of React components, sensible UI design, and a friendly development experience. It is supported in all major browsers. It provides pre-built components of React which can be used easily in any web application. In this article, we’ll learn about React Suite Cascader Container and Prevent Overflow.
A cascader is used for a single selection of data with a hierarchical relationship structure. The preventOverflow prop helps in positioning the cascader components in the scrolling container.
Syntax:
<PreventOverflowContainer>
{getContainer => (
<Cascader
preventOverflow
container={getContainer}
data={...}
...
/>
)}
</PreventOverflowContainer>
Creating React Application and Installing Module:
Step 1: Create a react application using the given command:
npm create-react-app projectname
Step 2: After creating your project, move to it using the given command:
cd projectname
Step 3: Now Install the rsuite node package using the given command:
npm install rsuite
Project Structure: Now your project structure should look like the following:
Example 1: Below example demonstrates the preventOverflow of Cascader Component in a container.
import "rsuite/dist/rsuite.min.css";
import { Cascader } from "rsuite";
import { useEffect, useRef } from "react";
const customData = [
{
label: "Data Structures",
value: 1,
children: [
{
label: "Queue",
value: 2,
children: [
{
label: "Priority Queue",
value: 3,
},
{
label: "FIFO Queue",
value: 4,
},
],
},
{
label: "Linked List",
value: 5,
children: [
{
label: "Circular",
value: 6,
},
{
label: "Double",
value: 7,
},
{
label: "Single",
value: 8,
},
],
},
],
},
{
label: "Algorithms",
value: 1,
children: [
{
label: "Search",
value: 2,
children: [
{
label: "Binary Search",
value: 3,
},
{
label: "Linear Search",
value: 4,
},
],
},
{
label: "Sorting",
value: 5,
children: [
{
label: "Bubble Sort",
value: 6,
},
{
label: "Selection Sort",
value: 7,
},
{
label: "Insertion Sort",
value: 8,
},
],
},
],
},
];
function PreventOverflowContainer(
{
children,
height = 500
}) {
const container = useRef();
const content = useRef();
const containerStyle = {
overflow: 'auto',
position: 'relative'
};
const contentStyle = {
height: '400%',
width: '230%',
justifyContent: 'center',
alignItems: 'center',
display: 'flex',
flexWrap: 'wrap'
};
useEffect(() => {
container.current.scrollTop =
content.current.clientHeight / 2 - 60;
container.current.scrollLeft =
content.current.clientWidth / 2 -
container.current.clientWidth / 2;
}, [container, content]);
return (
<div style={
{
...containerStyle,
height
}} ref={container}>
<div style={contentStyle} ref={content}>
{children(() => container.current)}
</div>
</div>
);
}
export default function App() {
return (
<div>
<div style={
{
textAlign: "center"
}}>
<h2>GeeksforGeeks</h2>
<h4 style={
{
color: "green"
}}>
React Suite Cascader Container
and Prevent Overflow
</h4>
</div>
<div style={
{
padding: 20,
textAlign: "center"
}}>
<div>
<PreventOverflowContainer>
{getContainer => (
<Cascader
preventOverflow
placement={'bottomStart'}
style={{ width: 224 }}
container={getContainer}
data={customData}
/>
)}
</PreventOverflowContainer>
</div>
</div>
</div>
);
}
Output:
Example 2: Below is another example that demonstrates the preventOverflow of cascader component with a subtle appearance in a container.
import "rsuite/dist/rsuite.min.css";
import { Cascader } from "rsuite";
import { useEffect, useRef } from "react";
const customData = [
{

value: 1,
children: [
{
label: "Queue",
value: 2,

},
{
label: "FIFO Queue",
value: 4,
},
],
},
{
label: "Linked List",
value: 5,
children: [
{
label: "Circular",
value: 6,
},
{
label: "Double",
value: 7,

label: "Single",
value: 8,

},

},

value: 1,
children: [

},
];

container.current.clientWidth / 2;
}, [container, content]);
return (
