Solution 1

You can fix this easily now

Add to ion-select element:

[interfaceOptions]="{cssClass: 'my-class'}"

Add to css:

.my-class .alert-wrapper {
    max-width: 94% !important;
}

Solution 2

Yes, you can use cssClass in option like this:

// In your component
daysOptions = {
    cssClass: 'my-class',
    ...,
}

Then in css you can do what you want eg:

.my-class .alert-wrapper {
    max-width: 94% !important;
}

Thank's to ionic docs: https://ionicframework.com/docs/api/components/alert/AlertController/#advanced

I needed a color selector couple of months ago but I couldn’t find any. The only way to do this was using custom CSS. I tried adding CSS classes to ion-select and ion-option but the classes doesn’t get reflected in the generated output. So the only way to apply the custom CSS to ion-select and ion-options is by using the parent element and some JS.
