Collapse | Vanilla

The collapse component is used to collapse an element on the page.

Note: The collapse element must wrap everything inside of it otherwise the collapse animation is not smooth.

Add the classname dk-collapse and a unique ID to the element that needs to be collapsed. To have the collapsed content shown initially add the classname dk-show to the element.

The collapse element can be toggled, shown or hidden either by JavaScript or by adding the data-collapse-target attribute to a different element on the page.

Control with Attributes

To set an element as the controller for the collapse add data-collapse-target="#collapseID". By default when clicked it will toggle the collapse. You can force the element to show or hide the collapse by adding the data-collapse-action="hide" or data-collapse-action="show" attributes.

Control with JavaScript

Digit provides a global helper function to make it easier to programmatically open and close a collapse.

// Using a string selector
dk.collapse("#idOfCollapse").toggle();
dk.collapse("#idOfCollapse").hide();
dk.collapse("#idOfCollapse").show();

Accordion

Usage Notes:

Accordion Panel:
- Every panel is wrapped by .dk-accordion__panel
Accordion Trigger Button:
- Has a unique ID.
- Has the aria-controls attribute and that attribute has the id of the panel it opens.
- Inside the button you have the .trigger__title SPAN as well as the .trigger__icon SPAN.
Accordion Collapse:
- Has the class of dk-collapse and its only child element is the .dk-accordion__content DIV. Without this the animation to open and close the accordion panel will not be smooth.
- Has a unique ID.
- Has region of "role": role="region"
- Has the aria-labeledby attribute set to the ID of the trigger that is controlling it.

JS

If the accordion markup is not on the page when the global.js file from digit runs the accordion won't automatically bootstrap. You will have to manually init the accordion.

dk.accorion("cssSelectorOfAccordion");

Default Open Panel

To set an accordion panel to be open by default you must set the aria-expanded attribute on the panel trigger to be true

Allow Multiple Panels

By default only one accordion panel can be open at a time but by adding the data-allow-multiple attribute to the outermost .dk-accrodian element the accordion will allow multiple panels to open at once.

This is one style of button to indicate additional text or elements in a long description. Put it below a collapse component.

Add DIV with CLASS dk-show-more
Inside, add a BUTTON with CLASS dk-show-more__button
Set data-collapse-target to the ID of the collapsing section
Inside the button add:
- dk-show-more__more SPAN with text "More"
- dk-show-more__less SPAN with text "Less"
