Hi @Marcel_Szimonisz ,
Thank you for your response. I got to know the functions which are used in AEM and how content is pulled. However, I am more interested to know if a user can create own jssp code and call the same from an input form as <input type="jssp page name"/> similar to how aemContentPicker jssp page is called from delivery input form.
Could you please let me know if you have any idea on that?
I tried creating a jssp and calling it from an input form but it is not working.
