I recently started working with October CMS. I found on the Internet a kind of solution to my problem link But I did not understand how I can adapt the solution to my own
My form is actually a Mapbox map in which the user draws polygons, adds any information to the polygon, such as the color of the polygon and a description. Before saving, I perform a few operations on the polygons.
Something like: p_id: [choised from select], polygons_json: [0:[geo],1:[geo],2:[geo]], descriptions_json: [0:[desc],1:[desc],2:[desc]] .
I noticed that for this they use hidden fields in which data is saved. I was also puzzled by the use of JS
I used the Builder plugin and edited it manually,
