Making correlation as a function of drag and drop

[Abdullah]

Request for Guidance in Our new Module:
The core functionality of our new modul (Composite-SEM) is fine, we are currently working on enhancing the user interface and would greatly appreciate some expert guidance. We are specifically trying to implement a "model relationships" selection feature, similar to the "Endogenous model" option in the semlj module.

I have attempted to replicate this functionality within my module but haven't been successful so far. Given your expertise, any advice, pointers, or documentation you could share on the best approach to achieve this would be incredibly helpful and would ensure the module meets the high standards of the jamovi library.
Here is how SEMlj is linking varibles

However, the best we could is opening a line where the user should "write" the relationship, which we want to avoid and replace with a drag and drop functionality.

I am looking forward to your feedback on the submission and any suggestions you might have regarding the technical implementation mentioned above.

Thank you for your time and for the amazing work you do with jamovi.
