Combobox opening under modal

[huineng]

It's getting quite messy , spent whole day and still not working

I have tried to implement the combobox with 2 alternatives ..

1. using the itemValueKey.. but here i hit the problem as you also have on your demo webpage
   https://angular.carbondesignsystem.com/?path=/story/components-combobox--with-reactive-forms

now clear that item or select any other value
in case you clear that item, whatever you select is not shown on screen

or if you don't clear, the value always stays the same

see the "selected"

Please help me out urgently , i'm promoting this library but with every update , i think new problems are created

2. without itemValueKey

i'm not even sure where to start, maybe related with your upgrade to angular 10 (which i was using when you were not yet on ng10 ) and your previous version WAS working , so it might be your upgrade to angular 10

So i had to change to using "temValueKey" that at least didn't give me any error ( just the bug above)

this is the bug i got

  "TypeError: Cannot assign to read only property 'selected' of object '[object Object]'",
     "    at DropdownList.push.8a99f462d6cebb67ffa6.DropdownList.doClick )",
     "    at Object.eval [as handleEvent] (ng:///DropdownModule/DropdownList.ngfactory.js:66:23)",
     "    at handleEvent ",
     "    at callWithDebugContext"

thanks

@huineng was the issue solved by #1539?

[huineng]

yes only this remains https://angular.carbondesignsystem.com/?path=/story/components-combobox--in-modal

I'm not sure what's going on with the z-index there 😱 As a work around you should be able to target .bx--list-box--expanded and give it a high enough z-index ... We may want to consider explicitly adding it to the styles to sort out these edge cases 🤔

[huineng]

For me you can close it, i don't have that problem with my apps, i just thought it might be an issue in the library

[cal-smith]

Gotcha 👍 I'll leave it for the moment, since it seems like something that can be fixed generally

Should be fixed with carbon-design-system/carbon#8107
