Question
The general idea is to have a searchbar that when selected brings up a dropdown menu for a list of options, then the user can type and the list will shrink according to the matching results. I have already implemented all the basic logic for the searching part but the issue I keep having is the dropdown not behaving how I would like. This implementation with ItemList works flawlessly on its own but when brought into a UI to actually use this searchable dropdown it pushes all the other UI elements out of the way where the dropdown is because it is part of the UI. I tried making this work with nearly every variation of the Window subclasses (particularly the PopupMenu and PopupPanel) but they all had an issue where the focus was take away from the LineEdit as soon as the popup was shown to the user. I tried grabbing focus back to the LineEdit in countless ways but none worked. Not even calling grab_focus() or grab_click_focus() in an infinite loop worked.
I have a video showcasing the desired result but I am not allowed to post it so apologies for that.
