list: the new ListController behavior no longer waits for event.preventDefault asynchronously because it was causing keyboard navigations to scroll the page.
list:<md-list-item> now uses slots instead of properties and has removed many prescriptive items (such as avatar, image, and video items). The default slot can be used for any custom content. html <md-list-item> <div slot="overline">OVERLINE</div> <div slot="headline">First line</div> <div slot="supporting-text">Second+ lines</div> <div slot="trailing-supporting-text">Trailing</div> <md-icon slot="start">star</md-icon> <md-icon slot="end">star</md-icon> </md-list-item> Add type="button" or type="link" for interactive list items.
menu: Several enums in menu had their values changed from SCREAM_CASE to kebab-case to follow style guide. They are NAVIGABLE_KEYS -> NavigableKey, SELECTION_KEY -> SelectionKey, CLOSE_REASON -> CloseReason, KEYDOWN_CLOSE_KEY -> KeydownCloseKey
menu,select: refactor fixed property to positioning="fixed" in Menu and menuFixed to menuPositioning="fixed"
menu: This change refactors menu-item to no longer subclass or import from list-item. It also refactors it to use md-item directly which means that the API of menu item has moved from properties to slots. start-* and end-* slots are now just start and end, many tokens are now gone in favor of slotting. headline property is now a slot="headline" slot. Typeahead search text can now be set via typeaheadText which defaults to the slotted headline textContent. select-option now has the displayText which is used to display text in the md-select when the option is selected; defaults to the slotted headline textContent.
menu: We have deleted md-sub-menu-item. Instead it is recommended to use md-sub-menu which can have md-menu-item[slot=item] and md-menu[slot=menu] slotted into it. This makes sub-menu-item accessible for screen readers using linear navigation
menu: Menu no longer uses md-list internally which means the list-related properties such as list-tabindex and type should now be on the host of md-menu. The new attributes should be tabindex and role respectively.
iconbutton: Replace container-size tokens with container-width and container-height.
list: the noninteractive property has been replaced by the interactive property, and by default, a list-item will no longer show a ripple or focus ring. What to change:
To preserve prior default behavior, add the interactive attribute explicitly.
Any setting of a truthy noninteractive attribute or property can be removed as it's the new default behavior.
menu: rename corner and focus state values lowercase with dashes
chips: chips now follow the aria toolbar pattern. Chip sets are toolbars and chips are buttons or links. Filter chips are toggle buttons. What to change:
Remove type attribute from <md-chip-set> (you can mix and match chip types!)
Remove single-select from <md-chip-set>. Use JS to control filter chips if single selection is required. Radio filter chips will come in a future update.
Disabled chips CAN be focused with the keyboard if always-focusable is set.
Filter chips no longer dispatch a "selected" event. Listen to "click" and use event.target.selected instead.
ArrowUp and ArrowDown no longer navigate between chips. These are reserved for chip actions, like dropdown menu chips.
list,menu,select: the data-variant=".." selectors in list-item and all variants have been removed in favor of their respective slots. e.g. a slotted icon of the form md-icon[slot=end][data-variant=icon] should now be md-icon[slot=end-icon].
menu: menu selected container color changed to secondary-container
list:
list: Aria and roles on List have been moved to the host element. list-tabindex attribute should be migrated to tabindex attribute. type attribute should be migrated to role attribute.
list,menu,select: removed active from list-item, menu-item, and select-option. Instead, List uses tabindex to track whether something is focusable.
select:option.selected no longer reflects. Set the attribute instead if relying on the attribute for styles/queries.
dialog: if overriding margin on a dialog's content, swap it to padding. If a dialog's slotted first or last child has built-in margin (such as <h3> or <p>), remove the top/bottom margin as needed (since margin swapped to padding, there's no more margin collapsing).
tabs: Rename the selected index property on md-tabs to activeTabIndex (active-tab-index attribute). Rename select-on-focus to auto-activate
typography: composite -type tokens are no longer supported. Use discrete -font, -size, -line-height, and -weight tokens instead.
tabs: replace label-text-type tokens with -font, -size, -line-height, and -weight
tabs: rename selected to active for primary and secondary tabs.
textfield: replace slot names leadingicon and trailingicon with leading-icon and trailing-icon
select: replace leadingicon and trailingicon slot names with leading-icon and trailing-icon
navigationtab: change slot names activeIcon and inactiveIcon to active-icon and inactive-icon
