Dropdown sort

Who can I sort alphabetically by value a dropdown list (combo box)? I noticed that it sorts by ID but I need to have it by value

I mean in a datatable

Any follow please?

Currently it can be done through onBeforeSort event usage

In Webix 1.7 we will add the “text” sorting mode. In such mode datatable will be sorted by the visible text
