Support CoreUI Development

CoreUI is an MIT-licensed open source project and is completely free to use. However, the amount of effort needed to maintain and develop new features for the project is not sustainable without proper financial backing.

You can support our Open Source software development in the following ways:

  • Buy the CoreUI PRO, and get access to PRO components, and dedicated support.
  • Became a sponsor, and get your logo on files or each site of this documentation
  • Give us a star ⭐️ on Github.

React Popover Component

Documentation and examples for adding React popovers, like those found in iOS, to any element on your site.

Other frameworks

CoreUI components are available as native Angular, Bootstrap (Vanilla JS), and Vue components. To learn more please visit the following pages.


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

Four directions#

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

2 content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
3 placement="top"
4 >
5 <CButton color="secondary">Popover on top</CButton>
6 </CPopover>
7 <CPopover
8 content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
9 placement="right"
10 >
11 <CButton color="secondary">Popover on right</CButton>
12 </CPopover>
13 <CPopover
14 content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
15 placement="bottom"
16 >
17 <CButton color="secondary">Popover on bottom</CButton>
18 </CPopover>
19 <CPopover
20 content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
21 placement="left"
22 >
23 <CButton color="secondary">Popover on left</CButton>
24 </CPopover>


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.

1--cui-popover-zindex: #{$zindex-popover};
2--cui-popover-max-width: #{$popover-max-width};
3--cui-popover-font-size: {$popover-font-size};
4--cui-popover-bg: #{$popover-bg};
5--cui-popover-border-width: #{$popover-border-width};
6--cui-popover-border-color: #{$popover-border-color};
7--cui-popover-border-radius: #{$popover-border-radius};
8--cui-popover-inner-border-radius: #{$popover-inner-border-radius};
9--cui-popover-box-shadow: #{$popover-box-shadow};
10--cui-popover-header-padding-x: #{$popover-header-padding-x};
11--cui-popover-header-padding-y: #{$popover-header-padding-y};
12--cui-popover-header-font-size: {$popover-header-font-size};
13--cui-popover-header-color: #{$popover-header-color};
14--cui-popover-header-bg: #{$popover-header-bg};
15--cui-popover-body-padding-x: #{$popover-body-padding-x};

19--cui-popover-arrow-height: #{$popover-arrow-height};
20--cui-popover-arrow-border: var(--cui-popover-border-color);
