How to get default values in <search-selectable> while open a form(from localstorage)?

Hi guys, i need a little help with . I’ll give you a code and will explaint what I need to do.

<select-searchable okText="Odaberi" cancelText="Otkaži"
                           searchFailText="Nema rezultata"

WIth this code I’ve got a list of an items from array, and it’s ok. But I need to get a default value for certain account, such as AIR CONDITION > account number 010, and if user want to change it or edit it can do that within list. Something like binding with *ngFor.
Thanks a lot for help.
