Webix List doesn't show all the data

If the data given to list has a property id and if its an object, the list doesn’t shows all the entries.

because any {object}.toString() equals [object Object]. you can try to JSON.stringify keys before setting data and JSON.parse when need to get key

Thanks for responding.
Is there any way to stringify the data before giving it to the list, in dynamic load?

you can implement custom datatype https://webix.com/snippet/2f753f5b
