@Hypercubed , @marjan-georgiev @earshinov @amcdnl @seandgrimes ...
In the form-builder demo (https://swimlane.github.io/ngx-dnd/builder#builder-demo), would you please add few source items and also add restrictions

Source Items like

1. Accordion(can be container just as same as section only), and the restriction could be like a section could not be dropped in the accordion but the accordion can be dropped in the section.

form controls like
1.Dropdown
2.Datepicker
3.Radio button

let's say restrictions could be

1. a date picker, dropdown can be dropped into Accordion not in section
2. String and Number can be dropped into Section
3. radio button can be dropped into both section and accordion
4. date picker, dropdown, string and Number cannot be dropped into 'builder-target' dropzone
5. and as mentioned above, accordion can be dropped in root container, section
6. section can only be dropped into 'builder-target'

It would be great if you could provide me a at least a Stack blitz URL for this implementation...I tried a lot from my end to meet the implementation but could not able to achieve it.
