Add a menu button that toggles the panel's (also referred to as a sidebar) collapse state. When the screen is wide enough, animate the transition. The menu icon from OOUI is copied into Vector to avoid two ResourceLoaders modules (collapseHorizontal icon isn't ready for inclusion in the OOUI icon pack and ResourceLoaderOOUIIconPackModule doesn't support images). Additional polish and collaboration is needed but this patch fulfills the scope of its referenced task.

|
|
// Notes:
|
|
//
|
|
// - Usage requires three elements: a hidden checkbox input, a button, and a show / hide target.
|
|
// - By convention, the checked state is considered expanded or visible. Unchecked is considered
|
|
// hidden.
|
|
// - Please see additional documentation in checkboxHack.js for example HTML and JavaScript
|
|
// integration.
|
|
//
|
|
// Example supplemental styles (to be added on a per use case basis):
|
|
//
|
|
// - Animate target in and out from start (left in LTR) to end (right in LTR):
|
|
//
|
|
// .mw-checkbox-hack-checkbox:not( :checked ) ~ .mw-checkbox-hack-target {
|
|
// // Turn off presentation so that screen readers get the same effect as visually
|
|
// // hiding. Visibility and opacity can be animated. If animation is unnecessary, all
|
|
// // of this can be replaced with `display: none` instead to avoid hidden rendering.
|
|
// visibility: hidden;
|
|
// opacity: 0;
|
|
// @timing: @transition-duration-base ease-in-out;
|
|
// .transition( transform @timing, opacity @timing, visibility @timing; );
|
|
// .transform( translateX( -100% ) );
|
|
// }
|
|
//
|
|
// - Show / hide the target instantly without animation:
|
|
//
|
|
// .mw-checkbox-hack-checkbox:not( :checked ) ~ .mw-checkbox-hack-target {
|
|
// display: none;
|
|
// }
