Examples#

Live demo#

<CPopover
  title="Popover title"
  content="And here’s some amazing content. It’s very engaging. Right?"
  placement="right"
>
  <CButton color="danger" size="lg">Click to toggle popover</CButton>
</CPopover>

Four directions#

Four options are available: top, right, bottom, and left aligned. Directions are mirrored when using CoreUI for React in RTL.

<CPopover
    content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
    placement="top"
  >
    <CButton color="secondary">Popover on top</CButton>
  </CPopover>
  <CPopover
    content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
    placement="right"
  >
    <CButton color="secondary">Popover on right</CButton>
  </CPopover>
  <CPopover
    content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
    placement="bottom"
  >
    <CButton color="secondary">Popover on bottom</CButton>
  </CPopover>
  <CPopover
    content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
    placement="left"
  >
    <CButton color="secondary">Popover on left</CButton>
  </CPopover>

Custom popovers#

You can customize the appearance of popovers using CSS variables. We set a custom style to scope our custom appearance and use it to override some of the local CSS variables.

const customPopoverStyle = {
  '--cui-popover-max-width': '200px',
  '--cui-popover-border-color': 'var(--cui-primary)',
  '--cui-popover-header-bg': 'var(--cui-primary)',
  '--cui-popover-header-color': 'var(--cui-white)',
  '--cui-popover-body-padding-x': '1rem',
  '--cui-popover-body-padding-y': '.5rem',
}
return (
  <CPopover
    content="This popover is themed via CSS variables."
    placement="right"
    title="Custom popover"
    style={customPopoverStyle}
  >
    <CButton color="secondary">Custom popover</CButton>
  </CPopover>
)

Dismiss on next click#

Use the focus trigger to dismiss popovers on the user's next click of a different element than the toggle element.

<CPopover
  content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
  placement="right"
  title="Dismissible popover"
  trigger="focus"
>
  <CButton color="danger">Dismissible popover</CButton>
</CPopover>

Usage#

Disabled elements#

Elements with the disabled attribute aren't interactive, meaning users cannot hover or click them to trigger a popover (or tooltip). As a workaround, you'll want to trigger the popover from a wrapper <div> or <span>, ideally made keyboard-focusable using tabindex="0".

For disabled popover triggers, you may also prefer trigger={['hover', 'focus']} so that the popover appears as immediate visual feedback to your users as they may not expect to click on a disabled element.

<CPopover
  content="Disabled popover"
  placement="right"
  trigger={['hover', 'focus']}
>
  <span className="d-inline-block" tabIndex={0}>
    <CButton color="primary" disabled>Disabled button</CButton>
  </span>
</CPopover>

Customizing#

CSS variables#

React popovers use local CSS variables on .popover for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

--cui-popover-zindex: #{$zindex-popover};
--cui-popover-max-width: #{$popover-max-width};
@include rfs($popover-font-size, --cui-popover-font-size);
--cui-popover-bg: #{$popover-bg};
--cui-popover-border-width: #{$popover-border-width};
--cui-popover-border-color: #{$popover-border-color};
--cui-popover-border-radius: #{$popover-border-radius};
--cui-popover-inner-border-radius: #{$popover-inner-border-radius};
--cui-popover-box-shadow: #{$popover-box-shadow};
--cui-popover-header-padding-x: #{$popover-header-padding-x};
--cui-popover-header-padding-y: #{$popover-header-padding-y};
@include rfs($popover-header-font-size, --cui-popover-header-font-size);
--cui-popover-header-color: #{$popover-header-color};
--cui-popover-header-bg: #{$popover-header-bg};
--cui-popover-body-padding-x: #{$popover-body-padding-x};
--cui-popover-body-padding-y: #{$popover-body-padding-y};
--cui-popover-body-color: #{$popover-body-color};
--cui-popover-arrow-width: #{$popover-arrow-width};
--cui-popover-arrow-height: #{$popover-arrow-height};
--cui-popover-arrow-border: var(--cui-popover-border-color);

How to use CSS variables#

const vars = {
  '--my-css-var': 10,
  '--my-another-css-var': 'red',
}
return <CPopover style={vars}>...</CPopover>
