  Hi,

  To pre-select some items, simply set their checkedMemberPath to true before the MultiSelect is loaded. Please refer to the sample link below for reference:

  Hi,

  The checkedMemeberPath property is used to get or set the property which will be bound to the checkbox of MultiSelect. For example, if you have data like:

  [{ id: 1, name: 'XYZ', active: true}, ...]
  

  and you have set the checkedMemberPath property to active, then if this item will be checked, then active will become true and vice-versa.
  
  If you have not set the checkedMemberPath property, then the MultiSelect uses $checked as the property by default.
  
  In your case, since you are not aware So, in order to pre-select some items, just set the $checked property to true.

  I hope this clears your doubts.

  ~regards
