        @keshava219  You can create datasource node structure with sling:resourceType of datasource as sling:resourceType (String) = /bin/dropdownList ( i.e. Path of the servlet implementing the data source for dynamic value). It will give the desire result of a dynamic dropdown as you can see below the screenshot.

         

            

         

        For DataSource Servlet (/bin/dropdownList) Implementation you can refer to below articles:

        Hope this helps

        Thanks

          Hi @keshava219 

          you should write dialog js so that wehn you change on dialog level at that time only dropdown value get changed (at the same time )---> Js will help you on that...

           

          But if you want to pass the value in servlet , it can be done like below mentioned code snippet . but this would not be "on the fly" ..Suppose value is 5 .after dialog submission only your dropdown items count  would be 5   ..when you made it suppose 6 then submit dialog again and open it again then only 6 items you will be able to see ..In backedn it will work like that 

           

          as you registered servlet with path ...just read the  dailog values of your field "Number of Articles to Show " in your servlet 

          smething like this you can do 

           

          then you can use this value and put the logic to just those many dropdown selection items .

           


          String cmptOnPage = req.getPathInfo().toString();
          String actualPath = cmptOnPage.substring(cmptOnPage.lastIndexOf("/content"), cmptOnPage.length());
          ValueMap actualResourceValueMap = req.getResourceResolver().getResource(actualPath).adaptTo(ValueMap.class);
          String dialogVlaues =actualResourceValueMap.get("text", String.class);

          logger.info("dialogVlaues path "+dialogVlaues);
