# NativeSelectExt7 Add-on for Vaadin 7 and 8



NativeSelectExt7 is a UI component add-on for Vaadin 7+8.

It allows disabled entris in the NativeSelect component.



In vaadin 8 the  component is based on the com.vaadin.v7.ui.NativeSelect version,

so you will have to include the vaadin 7 compatibility layers in your v8 project.



You can modify the style of the disabled items, by providing your own css

rules. Make sure to test the css rules, since not all browser allow all rules

for the option drop down entries.



Current rules are:



    select option:disabled {

        background-color: lightgray;

        color: black;

    }

Use "Permanently mark goal resources in pom.xml as ignored in Eclipse build" quick-fix to mark these errors as permanently ignored in your project. Do not worry, the project still works fine. 



### Debugging server-side



If you have not already compiled the widgetset, do it now by running vaadin:install Maven target for NativeSelectExt7-root project.

To debug project and make code modifications on the fly in the server-side, right-click the NativeSelectExt7-demo project and choose Debug As > Debug on Server. Navigate to http://localhost:8080/NativeSelectExt7-demo/ to see the application.



### Debugging client-side



Debugging client side code in the NativeSelectExt7-demo project:

  - run "mvn vaadin:run-codeserver" on a separate console while the application is running

  - activate Super Dev Mode in the debug window of the application or by adding ?superdevmode to the URL

  - You can access Java-sources and set breakpoints inside Chrome if you enable source maps from inspector settings.
