    Hi @dilli_babu_22 , not sure what the ask is here but if you want some additional data to your java servlet, you can add properties to the node and read them in your servlet by getting resource valuemap.

    Hope this helps,

    Thanks,

    Krishna

      Hi @dilli_babu_22 , Your question is a little confusing, but as far as I understand, below are the solutions.

      If your data source structure is as below and you want to get the value of the tag path in the servlet class, then you can get it with the help of a resource.

      <!-- # cq:dialog xml -->
      <items jcr:primaryType="nt:unstructured">
      <colorTags
              jcr:primaryType="nt:unstructured"
                      sling:resourceType="granite/ui/components/coral/foundation/form/select"
                      fieldDescription="Select the color tags"
                      fieldLabel="Color Tags"
                      multiple="{Boolean}true"
                      name="./colorTags">
      <datasource
                  jcr:primaryType="nt:unstructured"
                          sling:resourceType="/bin/colorTagLists"
                          tagsPath="/content/cq:tags/learning/color"/>
      </colorTags>
      </items>
      <!-- # cq:dialog xml -->

      Getting tagsPath in servlet class :

      resourceResolver = request.getResourceResolver();
              pathResource = request.getResource();
              resourceList = new ArrayList<>();

      /* Getting AEM Tags Path given on datasource Node */
      String tagsPath = Objects.requireNonNull(pathResource.getChild("datasource")).getValueMap().get("tagsPath", String.class);
      assert tagsPath != null;

      Please refer to this article for full details - https://unlocklearning.in/dynamic-dropdown-in-aem/ 

      I hope this could help you!!!

      Regards

      Shiv

            Hi,

            The datasource loads the dropdown at page/dailog load. If you want to change the values in the second dropdown list, you have to do it on the change event. This can only be done using Javascript.
