Question

How can you implement a unique ID for Custom Coach Views which are used in a repeating manner e.g. CV placed inside a Table Column?

Answer 1

If you create a custom coach view and place it inside a repeating construct like Table the view index is not automatically added to the Coach View and you may get undesired results

One way to handle this is if you have a OOB CV inside your control you can piggy back on the id of that CV to set the id of the parent Coach View elelemts

var viewid = _this.context.viewid;
viewid += _this.context.element.getElementsByClassName("Vertical_Layout")[0].id;
_this.context.element.querySelectorAll("div")[0].id = viewid + "-example";
