[OutSystems UI Web] DropdownSelect not overflowing Modal - OutSystems UI Web v1.8.6

after searching for a solution I found a semi solution that brings another problem, and you can find them in the links below.

dropdown-not-overflowing-in-a-modal, dropdownselect-list-not-overflowing-outside-of-modal

So the issue there is the dropdown doesn't overflow inside a modal. So the solution discussed in those topics is to disable the modal overflow property, like this. 

.modal-content {
    overflow-y: unset !important;
.modal-wrapper {
    overflow: scroll;

The problem with this approach is that, by disabling the overflow, if you have a modal with more content besides the DropdownSelect, it will overflow out of the modal:

Without the fix above:

In other words, adding that CSS line breaks the modal responsiveness.

Any idea how to make this right?

Hi João,

To ignore the parent overflow settings, you can use position: absolute on the dropdown. This solution has some issues, though; you'll need to explicitly define the modal height and/or reserve some space for the dropdown to sit 'on top of', and you'll have to explicitly define the dropdown position relative to the modal (using top, left, etc). 

Haven't found a more elegant solution yet, but it should work.
