Highlighted Features

Refresh Theme without Code Change - Compact Theme

The new default Iceblue theme from 8.5 has brought you with a refreshed, ultra modern look and feel. For users upgrading from an older version, Iceblue Compact is now available in 8.6 bringing you a same refreshed modern look and feel, along with breeze-compatible font size, paddings, and margins. Yes, this means zero code upgrade!

For theme-pack theme users, all 24 theme pack themes have their corresponding compact theme. To apply a theme, just include the theme pack jar and specify the compact theme name, for example:

<library-property>
    <name>org.zkoss.theme.preferred</name>
    <value>iceblue_c</value>
</library-property>

• Each compact theme is named after the original theme name appended with "_c". For example, iceblue_c is the compact version of iceblue theme.

Other Enhancements

Improved Rendering Speed

In each new release we try to optimize our framework further to provide you with the best performance and usability. In ZK 8.6 we have specifically improved the rendering speed when opening a tree node; and when changing the model of a chosenbox.

Guide Users with a Pop-up Menuitem

If you wish to guide new users to click a specific menuitem or open a menupopup, ZK provides a way to hint them by highlighting the specific item:

menu.getMenupopup().setActive(i);

Packaging change: (Servlet 3) Web Fragment Rearranged

Web-fragment was included by default in the previous versions. We now make it more flexible and separated ZK web fragment into another artifact, so that you can decide to include it or not depending on your project requirement.
