How to add a created element in the CRM section using JavaScript?

Question

I want to add a created element in JS into CRM form. How could I do it and is it possible?

var body = Xrm.Page.ui.tabs.get("Tab").sections.get("Section");
var tbl = document.createElement('table');
body.appendChild(tbl); // I need to add created tbl into CRM section but feiling here 

Answer 1

Whatever you are trying is unsupported in Xrm context. Instead it's recommended to build a custom HTML web resource, build the table there.

The web resource can be embedded in the Xrm entity form section. This is totally supported.
