JET Drawer Layout

Description: A Drawer Layout adds expandable side contents (drawers) alongside some primary content. These drawers automatically swap 'reflow' and 'overlay' display mode based on width of the page and can be placed at the 'start', 'end' or 'bottom' edge. 


<oj-drawer-layout end-opened="true">

   <div slot="start">Start drawer content </div>
   <div slot="end">End drawer content </div>

   Main section content

</oj-drawer-layout>

JET Drawer Popup and Drawer Layout look similar, but are intended to be used for different purposes.

Use Drawer Layout

  • If you need to switch between the ‘reflow’ display mode (big screens) and ‘overlay’ (small screens).
  • If the drawer should only fill a specific part of the viewport rather than take its full height (start/end) or full width (bottom).
  • If modality is not required.

Use Drawer Popup

  • If you need to display ‘overlay’ drawers attached to the edge of the viewport that stretch over the full viewport height or width.
  • If you need modality.

Accessibility

It is developer’s responsibility to define respective aria properties to meet accessibility requirements. Use aria-labelledby, aria-describedby or aria-label attributes on drawer elements (slots of the Drawer Layout) to make them accessible.

aria-labelledby

If a drawer already has a visible title bar, the text inside that bar can be used to label the dialog itself. Set the value of the aria-labelledby attribute to be the id of the element used to title the drawer. If there isn't appropriate text visible in the DOM that could be referenced with aria-labelledby use the aria-label attribute to define the accessible name of an element.

aria-describedby

If the drawer contains additional descriptive text besides the drawer title, this text can be associated with the drawer using the aria-describedby attribute.

Reading direction

Setting the reading direction (LTR or RTL) is supported by setting the "dir" attribute on the <html> element of the page. As with any JET component, in the unusual case that the reading direction is changed post-init, the page must be reloaded.

Sizing

On mobile resolution side drawers stretch full-height. On non-mobile resolution side drawers stretch to Drawer Layout container's height. The bottom drawer always stretch to Drawer Layout container's width. The other axis dimension is not predefined. This dimension's size is determined by its content. If you want to set a custom size you can use units like px, rem, etc. However because there is no fixed-size parent percentages (%) won’t work, but you can use vw (viewport width) or vh (viewport height) units to achieve a similar effect.

  • Note the side drawer's built-in minimal width limit in the 'Overlay' mode.
  • Note that DrawerLayout animates opening and closing. However, it is app developer's responsibility to add animations for custom runtime changes to a drawer size. See the 'Sizing' cookbook demo for an example.

Events

ojBeforeClose

Triggered immediately before the drawer closes. Call event.preventDefault() in the event listener to veto the event synchronously, which prevents the drawer from closing. Call event.detail.accept(Promise.reject()); in the event listener to veto the event asynchronously, which prevents the drawer from closing.
Properties:

All of the event payloads listed below can be found under event.detail. See Events and Listeners for additional information.

Name Type Description
accept function This method can be called with an application-created Promise to cancel this event asynchronously. The Promise should be resolved or rejected to accept or cancel the event, respectively.
edge "end" | "start" | "bottom" edge from which the drawer slides into the layout.
reason "escapeKey" reason for closing the drawer

ojClose

Triggered immediately after the drawer closes.
Properties:

All of the event payloads listed below can be found under event.detail. See Events and Listeners for additional information.

Name Type Description
edge "end" | "start" | "bottom" edge from which the drawer slides into the layout.
value boolean opened value
