ejs-dropdowntree - Select all not setting display text for the dropdown

[Randall Wood]

Is there any option to select all items when component loads. I tried below. It selects all element but the display text on the dropdown is empty even though all checkbox are checked. Once I click on the dropdown to expand the display text populates.

  onCreate(event): void {

    this.ddTreeObj.selectAll(true);

  }
