Hello everyone, I have encountered the same issue as this developer. In my design, I need the width of the ExposedDropdownMenu to be the same as the TextField, but since ExposedDropdownMenu does not have a place to set PopupProperties, its maximum width is limited. Do you have any suggestions on how to solve this issue? Thank you.

My final solution was to copy the entire source code of ExposedDropdownMenuPopup, and in the createLayoutParams function, change the width from WindowManager.LayoutParams.WRAP_CONTENT to MATCH_PARENT, and add horizontal padding myself to solve the problem. I am sharing this solution for those who need it.

I copied the `androidx.compose.material3.internal.ExposedDropdownMenuPopup` and some related components to my own project, and changed the `width` from `WindowManager.LayoutParams.WRAP_CONTENT` to `MATCH_PARENT` on line 448. Then, you can just use `fillMaxWidth` for your desired popup content. I hope this solution will also help you solve the problem.
