I had an Inline Dialogue region with a page item being a Popup LOV. I needed to be able to select multiple values and be able to manually add more. But once I switched on multi-select the input field contracted to max-width 4px, the only way I found to fix that was to set the item to Stretch Form Item on and have it stretch out. But now came another problem. Now the manual entry was weird, you could only click on the first 4px(or the 4px after the last value if there were already values in there), and text you were writing was not visible until you stopped writing and clicked away.
So I was wondering how to fix this.
Running on APEX 19.2 btw, maybe this gets fixed in next versions
