Topic: Update multiselect options on event

anuragd7 free asked 5 years ago


In a modal element I have a form containing 2 multi-select elements, one after the other. Whenever I select or deselect one or more options selected in the first multi-select, I need to dynamically update the available options in the second multi-select. Currently even though I am changing the array containing the options , I am not able to update the options in the second multi-select in the view.

Hello,

How do you update the options array? Please note that you need to use spread operator (or other method that will change the reference to the array), not 'push' method. Only then Angular will trigger change detection on select options.

It is described in our documentation: https://mdbootstrap.com/docs/angular/forms/multiselect/#update-options
