Hello,

Webix provide no extra API for Ace editor - if the editor supports autocompletion or related suggestions (please refer to the editor API reference), this feature can be enabled after init as follows:

  webix.ui({      
    view: "ace-editor",
    id:"ace"
  });

  /*  getEditor(true) is a promise which is resolved 
      when the editor is loaded and rendered
  */
  $$("ace").getEditor(true).then(function(editor){
    /* any suppoted editor API can be called here */
  });
