they will behave stylistically as you tell them too,if tripForm and TinyEditor are div components they will behave as such and essentially will be the same as this,there will never be overlap unless you tell it to in your CSS

you have this

export class PageComponent extends Component {
  render() {
    return (
      <div className="container">
        <TripForm />
        <br />
        <TinyEditor />

Consequently, it’s quite common that React App Components get very deeply nested. We are talking dozens of levels deep, and often more. So if one of those deeply nested Components needs to show a modal, it’s going to face some serious CSS issues.,To do so we need to use the createPortal() method of ReactDOM. A portal is effectively such a sibling div, that bends the rule that all React components must be descendants of <div id=”root">. To do so we need to do the following:, Donations to freeCodeCamp go toward our education initiatives and help pay for servers, services, and staff.

      You need to enable JavaScript to run this app.

   <div id="root"></div>

   <div id="modal"></div> . //ADD THIS

The <Tooltip> and <Popover> components do not position themselves. Instead the <Overlay> (or <OverlayTrigger>) components, inject ref and style props.,Tooltip expects specific props injected by the <Overlay> component,This is generally provided by the Overlay component positioning the tooltip

function Example() {  const [show, setShow] = useState(false);  const target = useRef(null);
  return (    <>      <Button variant="danger" ref={target} onClick={() => setShow(!show)}>        Click me to see      </Button>      <Overlay target={target.current} show={show} placement="right">        {({ placement, arrowProps, show: _show, popper, ...props }) => (          <div            {...props}            style={{              backgroundColor: 'rgba(255, 100, 100, 0.85)',              padding: '2px 10px',              color: 'white',              borderRadius: 3,    ,            }}          >            Simple tooltip          </div>        )}      </Overlay>    </>  );}
render(<Example />);

A component with a render prop takes a function that returns a React element and calls it instead of implementing its own render logic.,More concretely, a render prop is a function prop that a component uses to know what to render.,Components are the primary unit of code reuse in React, but it’s not always obvious how to share the state or behavior that one component encapsulates to other components that need that same state.

<DataProvider render={data => (
  <h1>Hello {}</h1>

Below is a simple example of a no rows overlay component as a Hook:,Below is a simple example of overlay component as a Hook:,Simple No-Rows Overlay Component

export default props => {
   return (
       <div className="ag-custom-loading-cell" style={{paddingLeft: '10px', lineHeight: '25px'}}>
           <i className="fas fa-spinner fa-pulse"></i> <span> {props.loadingMessage}</span>

You can use a simple function to calculate the precise position for your popover. Then you can use it inside your Overlay component by only rendering this CustomPopover component as a child. ,Create a new component CustomPopover inside the root directory and add the following code:,Position the Popover Using a Custom Component

1n px create - react - app react - bootstrap - popover

Accessible modal dialog component for React.JS,The only required prop for the modal object is isOpen, which indicates whether the modal should be displayed. The following is an example of using react-modal specifying all the possible props and options:, Accessibility

This is our super complex route stack. All we do is have a named route with the componet to render.,We put our modal after the Navigator so we can render on top of it.,Hey now go get your modal on. Just remember, React is flexible. Sometimes you need to pass something up to render at the top. Yes slightly a pain, but it's a manageable pain.

Lets setup our app

var React = require("react-native");
var {
} = React;

var {
   height: deviceHeight
} = Dimensions.get("window");

A: You can add an overlay button on top of PSPDFKitView by setting its position offset in the containing view’s style.,In this modified version of the ManualSave component from our Catalog example, we overlay the “Save” button in the top-right corner of the view, like so:, Copyright 2010-2021 PSPDFKit GmbH.

class ManualSave extends Component {
  render() {
    return (
      <View style={{ flex: 1 }}>
          document={"PDFs/Annual Report.pdf"}
            backgroundColor: processColor("lightgrey"),
            showThumbnailBar: "scrollable"
          style={{ flex: 1, color: pspdfkitColor }}
            position: 'absolute',
            right: 10,
            top: 40,
            flexDirection: "row",
            height: 60,
            alignItems: "center",
            padding: 10
              onPress={() => {
                // Manual Save
