Each dashboard item can be customized, even at runtime without page submit!</p><p>The main advantage of the dashboard is that end-users of your APEX app can configure one or more dashboards at runtime without having to touch the region or page by a developer! This was not possible in APEX so far! Of course, the dashboard can also be used as a fixed region.</p><p>The plug-in requires an APEX 5.1.3 or newer and an Oracle 12c or newer. The Sample App requires an APEX 20.2 or newer. However, you can quickly install it in a free workspace on apex.oracle.com and then get started right away with the help of the Sample App!</p><p>The item dialog in the Sample App is just a very simplified example, of course in your application the respective data source (table, view, function...) and many setting options for the respective dashboard item can be offered there.</p><p>You can find a tutorial at<p>https:\/\/www.youtube.com/playlist?list=PL9daxiSwWyTbIm8fTa0ypeC6dFfMgXALq</p><p><b>Important clarification: My work in the development team of Oracle APEX is in no way related to my open source projects or the plug-ins here on apex.world! All plug-ins are built in my spare time and are not supported by Oracle!</b></p>",
