Hi,
I made a post yesterday and then found this which better explained my exact problem.
I’ve made a codepen https://codepen.io/johntom/pen/PopVGgg which has dataSource currently set to fetch remote data and dataSourceX which uses harcoded json data.
The default behavior using a fetch call will not display columns when clicking Customize Columns.
If you rename dataSource to dataSourcexx and rename dataSourceX (which uses hardcoded json) to dataSource you will then see it fuctioning.
Thanks,
John
