Vue Accordion Component

Build vertically collapsing accordions in combination with our Vue Collapse component.

Other frameworks

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

Examples

Click the accordions below to expand/collapse the accordion content.

Accordion Item #1

This is the first item's accordion body. It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the .accordion-body, though the transition does limit overflow.

Accordion Item #2

This is the second item's accordion body. It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the .accordion-body, though the transition does limit overflow.

Accordion Item #3

This is the third item's accordion body. It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the .accordion-body, though the transition does limit overflow.

<CAccordion>

      hiding via CSS transitions. You can modify any of this with custom CSS or overriding
      our default variables. It's also worth noting that just about any HTML can go within

Customizing

CSS variables

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

--cui-accordion-color: #{color-contrast($accordion-bg)};
--cui-accordion-bg: #{$accordion-bg};
--cui-accordion-transition: #{$accordion-transition};
--cui-accordion-border-color: #{$accordion-border-color};
--cui-accordion-border-width: #{$accordion-border-width};
--cui-accordion-border-radius: #{$accordion-border-radius};
--cui-accordion-inner-border-radius: #{$accordion-inner-border-radius};
--cui-accordion-btn-padding-x: #{$accordion-button-padding-x};
--cui-accordion-btn-padding-y: #{$accordion-button-padding-y};
--cui-accordion-btn-color: #{$accordion-color};
--cui-accordion-btn-bg: #{$accordion-button-bg};
--cui-accordion-btn-icon: #{escape-svg($accordion-button-icon)};
--cui-accordion-btn-icon-width: #{$accordion-icon-width};
--cui-accordion-btn-icon-transform: #{$accordion-icon-transform};
--cui-accordion-btn-icon-transition: #{$accordion-icon-transition};
--cui-accordion-btn-active-icon: #{escape-svg($accordion-button-active-icon)};
--cui-accordion-btn-focus-border-color: #{$accordion-button-focus-border-color};
--cui-accordion-btn-focus-box-shadow: #{$accordion-button-focus-box-shadow};
--cui-accordion-body-padding-x: #{$accordion-body-padding-x};
--cui-accordion-body-padding-y: #{$accordion-body-padding-y};
--cui-accordion-active-color: #{$accordion-button-active-color};
--cui-accordion-active-bg: #{$accordion-button-active-bg};

How to use CSS variables

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