Create Scaffolding in AEM

Create a scaffold, using the access Tools console http://localhost:4502/miscadmin and select Scaffolding in left tree; In the right pane select New, a dialog with single template Scaffolding Template appears. 
Enter title My Text Image. Click Create

1) Double click on My Text Image to open the scaffolding editor http://localhost:4502/cf#/etc/scaffolding/my-text-image.html. Click Sidekick -> Page tab -> Page properties and select the following

                       Target Template: The template used for page creation. In step 1 to create the page manually, we used a simple Basic Template.As we are generating pages of Basic Template select it
                       Target Path: The path where generated pages are stored

Here is the code for basic template page component jsp

2) After entering the details in page properties, a basic scaffold is created with Title to enter page title (stored as jcr:title) and Tags.

3) Every scaffolding has Dialog Editor to work on its form fields like Title above. Click on the Sidekick design mode (L shape at the bottom of sidekick) to access page having link for Dialog Editor. Click on the link to open Dialog Editor - http://localhost:4502/etc/scaffolding/my-text-image/_jcr_content/dialog.html

    Dialog in CRXDE Lite

4) Using the dialog editor we can add new properties for existing fields, but to add new fields a developer has to visit CRXDE; Access the created scaffold page in CRXDE http://localhost:4502/crx/de/index.jsp#/etc/scaffolding/my-text-image and add widget for Text field in the dialog - /etc/scaffolding/my-text-image/jcr:content/dialog/items/tab1/items/text ( you can copy an existing  richtext widget node available eg.  /etc/scaffolding/geometrixx/news/jcr:content/dialog/items/tab1/items/text)

The name of field is set to ./jcr:content/par/text/text. So any value entered for this field is stored in path /jcr:content/par/text/text relative to the newly created page

Similarly we need hidden fields for storing the value of sling:resourceType - foundation/components/text and textIsRich - true; so we create necessary hidden widgets

5) Similarly we need html5smartimage widget and hidden field for storing image specific values. As you can see the image specific values are stored under ./jcr:content/par/image relative to new page

The hidden field for storing Image Component resourceType

6) We have the scaffolding form now ready for creating pages http://localhost:4502/cf#/etc/scaffolding/my-text-image.html. Enter Title, Text, drag an Image from content finder, click Create and your page will be created.
