Opened an issue on the IgniteUi Github page with some code example here :https://github.com/IgniteUI/igniteui-angular/issues/6218

Hi Monika,

I will raise an issue on Github but I will keep this post as not answered until I get an actual solution.

I will make sure to post the solution here.

Thank you.

Hi Michael,

The "deselectallItems" is a Method of the IgxComboComponent, not of the IgxDropDownComponent.
