iron-elements

Basic building blocks for creating an application.

Roadmap

iron-list - the upgraded version of a virtualized infinite list, previously named core-list. ETA: Couple weeks.

Elements we're planning on building soon but haven't started yet

[Currently focused on getting all elements up to speed]

Elements we're not planning on building as part of this product line, but that one might be wondering about

A number of elements existed as core elements that are not in this product line:

core-action-icons - This wasn't really an element, and wasn't particularly heavily used.
core-animation - The animation-related elements that were part of core will be created as part of the neon product line.
core-docs - Deprecated: use iron-doc-viewer.
core-drag-drop - Not currently working on.
core-dropdown and core-dropdown-menu - These were confusing UI to have in core, so we've moved them to the paper element set for now and made them easier to customize. More on the thought process behind this change in the blog.
core-focusable - This has been re-implemented using Polymer behaviors - see for example the paper-radio-button-behavior in paper-behaviors.
core-item - This had UI opinion, so was re-implemented as paper-item.
core-layout - We're working on more stable, consistent layout elements.
core-overlay - This is re-implemented as a behavior, in iron-overlay-behavior.
core-popup-menu - This element wasn't particularly of unique value, so we're putting it away for now.
core-scroll-header-panel - This had UI opinion, so it's been moved to paper-scroll-header-panel.
core-splitter - This element was relatively trivial, so we've put it off for now.
core-style - This element is not useful with Polymer's new styling system. Check out the latest docs for more.
core-tooltip - This will become paper-tooltip.
core-menu - This had UI opinion, and will become paper-dropdown-menu.
